BSF admixtures help to maintain sustainability in concrete and cement

Both concrete and cement play an important role for several construction projects. Concrete is primarily formed with cement, water and grains of stone. Cement is developed by mixing calcium silicate with portions of aluminum and iron compounds.

The following construction video explains the total procedure for creating these materials.

This animated construction video also focuses on the functionality of concrete superplasticizer Glenium to make the best use of these materials for making concrete more flexible, long-lasting and resilient.

BASF Glenium superplasticizers enhance the structural properties of concrete as well as its eco-friendliness.

By applying BASF’s concrete admixture Glenium, up to 50 percent of the cement clinker is substitued with other materials. These materials consist of fly ash, a byproduct of coal-fueled electric power plants, or blast furnace slag obtained throughout steel production and recycled for these purposes. Thus, Glenium admixtures facilitates savings of up to 60 percent carbon in concrete production. So Glenium is very vital element to reduce carbon emissions in cement production.

Benefits of externally bonded reinforcement toward concrete & masonry

If concrete or masonry structures contain inadequate strength, externally bonded reinforcement provides good solution. Externally bonded fiber-reinforced polymer (FRP) composite systems is considered as the greatest substitute to traditional methods for solidification and retrofit. But the epoxy matrix of FRP systems is unstable to failure in high-temperature or aggressive surroundings.

Fabric-reinforced cementitious matrix (FRCM) systems are gaining popularity as a feasible substitute to FRP systems. FRCM systems are originated as a progression of FRP where the epoxy matrix is substituted with a cementitious matrix. With the cementitious matrix, FRCM systems can function efficiently under high temperatures, humidity, and ultraviolet radiation as compared to FRP systems. The cementitious matrix can significantly enhance the stability of the strengthening system in moist and chemically aggressive atmospheres, or in applications where vapor conformity of the strengthening system is necessary.

Properties of FRCM

FRCM systems are externally bonded strengthening systems which contain a fabric mesh implanted in a cementitious matrix. Identical to FRP systems, the fabric in an FRCM system bears the pressures transmitted from the concrete or masonry substrate via the cementitious matrix. The fabric usually includes meshes formed with carbon, alkali-resistant glass, basalt, or polymeric fibers (like polyparaphenylene benzobisoxazole, PBO), or hybrid systems.

The cementitious matrix applied in FRCM is non-shrinkable and executable in order that it can be smoothly shoveled as well as pervade the fabric mesh openings. Both hydraulic and non-hydraulic cements are applied. Sands graded superiorly (grain size less than 0.02 inch) can make the functionality of the fresh mix better as well as the saturation of the fabric mesh. The water-to-mortar ratio by weight generally varies from 15% and 25%. The mortar mix contains chopped fibers to lessen cracking that may occur due to compression in plastic. Organic compounds are also applied to manage the hardening rate and the functionality of the fresh mix, to enhance the bond to the fabric mesh, and to improve the mechanical properties. The fiber content is usually restricted to below 5% by weight of cement to achieve a fireproof matrix.

How to determine Shear Force & Bending Moment Equations for a beam

This informative construction video briefly explains how to determine equation for shear force & bending moment as well as how to sketchup their diagrams.

The shear force at a segment of a beam denotes the force that shears off the section and is procured like the algebraic sum of all forces together with the reactions functioning normal to the axis of the beam both to the left or right of the beam. As the beam is a inflexible structure, the force will be transmitted internally all along the beam. This internal force is called shear force.

Shear and bending moment diagrams belong to analytical tools applied in combination with structural analysis to facilitate accomplishing structural design by finding out the value of shear force and bending moment at a specified point of a structural element like a beam. These diagrams are used to define the type, size, and material of a structural member efficiently in a structure with the purpose of supporting a specified set of loads devoid of structural failure. Shear and moment diagrams are also useful to find out the deflection of a beam easily by applying either the moment area method or the conjugate beam method.

Importance of Augmented Reality (AR) Technology in Construction

With the emergence of Augmented reality (AR) technology, the process for designing and constructing a building is changed significantly.

AR is the latest technology that forms a compound view of real world atmospheres, overlaying an image produced through the user’s own real world view.

If AR applications are integrated with a smart device or wearable technology, it can generate a real scale 3D model of a building or particular room combined with your environments.

AR also facilitates the construction teams and consultants to significantly enhance the understanding of design discrepancies, outstanding tasks, safety issues, imperfect works and numerous other site-related variables.

If virtual reality allows the designers to visualize the appearance of a structure on a screen, AR leverages the real world to facilitate the user to perfectly preview how all the diverse areas of a plan organized together.

So, it becomes easier to detect conflict in design before the development of actual construction. Huge time is saved and risk is minimized. Therefore, the profitability of project is increased.

All the activities associated with construction site, which range from accomplishing and appraising a defect as well as notifying everyone of a safety issue, can be recorded and carried in a real world setting.

AR not only enhances the usability of site-related data, but also facilitate a uninterrupted user interaction and collaborative efforts in real-time.

As AR and GPS technology become superior, go into a construction site every day and being guided to the location of your outstanding tasks become possible.

Construction management platforms offer a superior level of collaboration amid all project stakeholders and this type of real time control can accomplish tasks more speedily.

By linking defects management functionality with AR elements, the process for recording, allocating and handling defects will be changed significantly.

With AR, a user can formulate and allocate real time data at the time of walking around a construction site, and generate tags noticeable to other users.

One can walk into a room through smart glasses and view all of the outstanding issues associated with that room by viewing AR tags. This will significantly improve the project quality and also the consciousness of possible safety concerns.

Brief explanation of wall footing design

Wall footing design is performed on the basis of some theories which must be taken into consideration at the time of designing. The first theory is to examine the soil pressure that is circulated linearly all through design process. This can be obtained, if resultant of soil pressure conforms with the resultant of soil force. Due to this, rotation of footing can be prevented. Usually, the following strength design method is applied while designing the footings.

WALL FOOTING DESIGN EXAMPLE STATEMENT

A 10” thick wall bears a service dead load of 8k/ft and service live load of 9k/ft. At the base of footing the permissible soil pressure is 5000psf and base of footing is 5’ underneath the present ground surface. Now your responsibility is to design the wall footing for;

This construction video highlights 17 various types of roof designs which are generally utilized in building designs, architecture and home construction. The video will provide great advantages to the architects, building designers and custom home builders.

Concrete compressive strength= f’c = 3ksi

Yield strength of steel = fy = 60ksi.

Soil density = 120lb/ft3.

SOLUTION:

Note: Typically low strength of concrete in footing is applied in columns. It necessitates the use of dowel to adapt this modification in strength.

STEP 1: ESTIMATE THE SIZE OF FOOTING AND FACTORED NET PRESSURE.

At the time of designing wall footing, generally one feet strip of the wall and footing is undertaken to simplify the calculation process. The permissible soil pressure is 5ksf. The permissible net soil pressure is 5ksf. As, the thickness of footing is unknown at this stage a acceptable thickness of footing equivalent to (1-1.5)x The wall thickness can be guessed.

1.5 x 9’’ = 13.5’’ take 13’’

STEP 2: FIND THE PERMISSIBLE SOIL PRESSURE

qn=5−[(1.083times0.150)+(5−1.083)times0.120]

[q_{n}=4.367 ksf]

[Area-of-footing=frac{8+9}{4.3676}]

Try 47’’ (3.91’) Wide footing

Factored Net Pressure = qnet = 6.138ksf

STEP 3: CHECK THE TOLERABILITY OF FOOTING DEPTH AGAINST SHEAR

Only one way shear or beam shear is substantial in wall footings. The crucial section for this type of shear is at distance ‘d’ from the face of wall. Where ‘d’ denotes the actual depth of footing.

Supposing that one will use #4 bar.

d = 13 – 3 – ¼ = 9.75″

The Tributary area for one way shear

Tributary area = Shaded area for one way shear

D = H – CLEAR COVER – 1/2 BAR DIAMETER

d = 13 – 3 -1/4

d = 9.75″
