Ideas to increase Durability and Quality for Brick Masonry

Brick Masonry is used in most construction projects, in one place or other. In many of the places it is a significant portion of the structure – often weight bearing. For this reason, it is imperative that the quality of the brick masonry remains top notch. Special care has to be taken to ascertain high durability and quality of it.

Here we list 5 key ideas about how you can increase the durability and quality of brick masonry.

1. Good Materials

To make something good, you must use top quality raw materials. It is imperative to use good quality bricks to construct good brick masonry. Use only hard, sound, well burnt and uncracked bricks. They should all have uniform color and shape. They should not have air holes or bubbles, stone lumps, and other deformities. Soak the bricks for two hours before using.

2. Proper laying

In the brickworks, the bricks must have been laying properly. While using them on site, make sure you have ‘true horizontal’ and ‘true vertical’ joints.

3. Proper bonding

Do not overuse the bricks, let them rest and form the bonding properly before loading them further. The generally prescribed height for bricklaying in one day is about 1.5 meters or about 7 feet, no more. Also, finished brickwork should be laid to rest to cure for 72 hours before starting other work on them.

Structural Design Guide for RCC Building

RCC stands for reinforced cement concrete. RCC building is the main structural member of the building like slabs, viz, beams, columns, and foundations which are made of reinforced cement concrete.

Design of the Foundation

Foundation design is a structural component of RCC.

1) Design of Foundation

Column footing is the most common type of foundation which is used. The strength of the foundation directly determines the structural stability of the building.

Foundation transfers loads of the building to the ground. The design of the foundation depends on the soil, structure, and load. Foundation has two types. One is the shallow foundation and another one is the deep foundation.

2) Calculation of loads in Foundation Design

It is very important for the structural design.

Types of loads

1. Self-weight of the column x Number of floors
2. Self-weight of beams per running meter
3. A load of walls per running meter
4. Total Load of the slab (Dead load + Live load + Self-weight)

For columns

The self-weight of Concrete is around 2400 kg per cubic meter. The self-weight of Steel is around 8000 kg per cubic meter. Let’s assume that a large column size of 230 mm x 600 mm with 1% steel and 3 meters standard height, the self weight of the column is around 1000 kg per floor, which is equivalent to 10 kN. So, the self-weight of the column to be between 10 to 15 kN per floor.

Solar roadways: the future of renewable energy

Solar Roadway

Hi folks we are back with another article. This article is about new advancement in street transportation. Essentially we utilized support solid streets and bituminous streets however nowadays there’s a pattern of making solar roadway.

These kinds of roadways are essentially utilized to produce electricity and to diminish a dangerous atmospheric deviation. The primary execution of this roadway is in France.

What Is the Solar Roadway?

Essentially solar roadway is the street surface which produces Electricity by utilizing solar photovoltaic cells. These cells are inserted beneath intense glass layers.

Presently a question arrived: what is a photovoltaic cell? Photovoltaic cell is the cell made by joining N-TYPE and P-TYPE silicon cells. N-TYPE silicons are those wherein silicon is doped with phosphorus and in P-TYPE silicon silicon is doped with boron. At the point when these two doped silicons get together with one another then it will make an intersection at the end of P-type and N-type silicon.

This will make parment electric field at the joint. Furthermore, when the sun’s vitality is applied in a type of light or warmth at an intersection then it will build potential and there will be a stream of electric flow this is the activity of solar photovoltaic cells.

Everything You Need to Know About Brick Work

Brick dividers are likely the most well-known structure components in development of a house in India. These dividers structure fundamental units for making rooms that make up a house. The dividers other than being space dividers are additionally primary components that move the heap of the rooftop to the ground.

Brick dividers are developed on strip spread or pontoon establishments that help the dividers. The dividers are built utilizing bricks and mortar. These can likewise be developed with different primary characteristics and thicknesses.

Brick dividers are built by getting bricks together with concrete mortar in game plans called English Bond, Flemish Bond or Rat Trap Bond. These bonds give diverse outer appearances to the divider. All development frameworks of brick dividers are such concocted that vertical cross joints in any layers are amazed. The bricks hence reinforce a strong mass that doesn’t part when the divider is stacked with live loads and dead loads.

Making Process of Column Stirrup

The reinforced concrete column is a structural member and is designed to bear loads. This column has two types of bar. One is a longitudinal bar and another one is a horizontal bar. Stirrups and ties are used in columns in the case of the horizontal bar.

Stirrups are also known as ring, shear reinforcement. Users have to calculate the cutting length of the bar and also have to calculate the number of stirrups to make stirrup for the column. After that users have to decide the size of the stirrup.

Step by step guide

1. To determine the size of the stirrup.
2. To calculate the cutting bar length for stirrup.
3. To calculate the number of stirrups.
4. To bend the bar in stirrup’s shape.

To determine the size of the stirrup

Let us say, The column size is 20″ x 40″. We all know that the concrete clear cover for reinforcement of column is 1½”.

So the length of the stirrup will be 40″-2×1½”=37″ and the width will be 20″-2×1½”=17″.

So the size of the stirrup is 37″x17″.

Basics about Hidden Beam

The depth of the hidden beam is equal to the thickness of the slab. A hidden beam is a type of reinforced concrete beam and it is also known as a concealed beam. It is a virtual beam.

This type of beam is inserted in the suspended slabs where engineers consider the slab thickness. This type of beam is given between the living and dining spaces. This hidden beam gives a level ceiling surface look. This hidden beam is used in commercial buildings.

Purpose of Hidden Beam

1. Using the greater span is allowed by the hidden beam for the slab.
2. It is provided for architectural aesthetic purposes in the building interior.
3. It is used for breaking a huge panel of a slab into a specific size.

Design of Hidden Beam

1. The design of this beam is the same as a conventional beam.
2. The depth of this beam is particular.
3. The slab thickness is not the same as a conventional beam.
4. It also is required to increase the reinforcement ratio dept width of the beam.

Bent Up Bar in Slab Cutting Length Calculation

If you are a civil engineer or a site engineer, it is essential for you to be able to calculate the cutting lengths of the reinforcement bars inside every load-bearing member. The same applies for the bent up bar in slab cutting length calculation. Today, we will try to explain it using a live example.

A bent up bar in slab is also called a crank. It is extremely important since it is used as the main reinforcement in the floor slab. It is provided in the bottom side of the slab, in the shorter side of the span. The main purpose of providing this bent up bar or crank is to transfer both the dead and live load of the slab to the beam. This load is then carried from the beam to the columns, from the column to the footing, and from the footing to the ground soil.

Why do you need to calculate bent up bar in slab

When you don’t have to deal with a much large construction area, the detailing of reinforcements in slabs can be done by bar bending schedules, by the person in charge of it. Those in charge of BBS or the bar benders can take care of the reinforcement detailing.

However, this method may not be perfect because the bar benders may not be vigilant in taking account of the cranks and bends, though they will give out some amount of cutting length. They might give some extra cutting length, but that will almost certainly not be enough for your bending requirement.

Design of an RCC Column for House

Columns are probably the most important load-bearing member of any structure, since they carry all the vertical loads of the building and transport it to the bottom of the structure, the foundation. For this reason, you have to design columns very carefully, with zero margin of error. Today, we will see the cost estimation design of an RCC column for house, taking an example.

Columns are defined as the main compression member of the structure, having more length than width or breadth. That is to say, a column will be bearing most of the loads coming down from above, and it will have an effective length much greater than its least lateral dimension.

We need to estimate the steel and concrete before we start making the column, because we have to be very precise in our work. The following is an example scenario where we calculate the steel design on an RCC column for houses, particularly for a given design.

Example Scenario

Let us say,

We are supposed to design a column for a house. The column is square in cross section, and it is short in comparison. There will be various forces acting on this column, but the major of this will be the axial load. The axial services compressive load acting on the column in question will be 600 KN.
