Learn to compute cement quota, brickwork volume & no. of fixes for a brick wall

This construction video tutorial will show the details of cement quota, brick work volume, number of fixes for a brick wall construction.

To calculate the brickwork volume, just apply the following formula :-

Total brickwork area x wall thickness
= 31.98 x 0.2 = 6.38 m3

The ratio of cement & mortar needed in brickwork is 1:3 (it can also be taken as 1:5 and 1:6).
Volume of brickwork = 6.38 m3
For 1 cubic meter of cement mortar, the volume of sand will be 0.2m3
For 6.38 cubic meter, the volume of sand will be 6.38 x 0.2 = 1.276 m3

For 1m3 cement mortar, the volume of cement will be = (0.2×1440)/3 (3 denotes last digit of ratio)
= (0.2 x 1440)/3 = 96 KGS
For 6.38 cubic meter, the volume of cement will be 6.38 x 96 = 612.48 KGS

To work out the number of cement bags, just divide it by 50 (as weight of 1 cement bag is similar to 50 Kg)
Therefore, 612.48/50 = 12.24 bags = 13 bags (approx.)

Definition of striking and pointing in brickwork

The variation among ‘striking’ and ‘pointing’ is given below :-

  • Striking stands for completing the mortar joints among the bricks which are placed freshly.
    • Pointing means employing a small amount of mortar into the face joint among bricks (either freshly placed or in old brickwork). In new brickwork, harder mortar is used in pointing to enhance weather protection on uncovered faces. In old brickwork, pointing is frequently applied for fixing up mortar joints which are worn by exposition to the elements.

Styles of finishing – Either striking or pointing, the elementary finishes remain the similar:

FLUSHED: It is very complicated to provide flush finishing because of the deformities of maximum mass produced bricks.

It can be obtained by drawing a strip of wood having dimension 12mm wide, 6mm thick and 100mm long along the joints as soon as the mortar has begun to run off.

This is possibly the simplest finish for a new diyer to attain.

WEATHERED: Weathered finishing emits rain water and is treated as relatively long-lasting but it is difficult for a diyer to achieve a good finish.

The joint is prepared by drawing the blade of a small trowel, sloping marginally inwards at the top, backwards along the joint, the top edge of the trowel start joining the bottom of the bricks over the joint being struck.

Toward vertical joints, the edge of the trowel is connected with one of the side bricks and is disposed by the similar amount like the horizontal joint. Maintain the direction of the vertical strikes identical all over a wall, or else it may appear odd.

HOLLOW KEY: Hollow key – It is built up by dragging a proper curved or round shaped piece of metal (i.e. tube or rod) along the joints.

STRUCK: Struck jointing is not recommended for exterior facings because it keeps the top most edge of the lower brick uncovered to the weather.

The actual method is equivalent to the weathered finish above, apart from that the trowel is angled inwards at the lowermost of each horizontal joint.

Necessary IS Codes for Functional Requirements In Buildings

A building code (alias building control or building regulations) stands for a series of rules which indicate the standards for constructed objects like buildings and nonbuilding structures. Buildings should abide by the codes to acquire planning permission, generally from a local council. The primary objective of building codes is to safeguard public health, safety and general welfare because they are associated with the construction and occupancy of buildings and structures.

Building codes are generally intended to be applied by architects, engineers, interior designers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants, and others. Codes regulating the design and construction of structures where adopted into law.

Given below, the detailed lists of all Indian Standard Codes which comprise of standardization in the area of functional requirements in buildings ranging from comfort point of view, for example space distribution, orientation, day-lighting, ventilation, acoustics and thermal comforts, from health and safety point of view, from the point of view of accessibility for persons with disability and from the point of view of energy requirements.

IS 1950:1962 Code of practice for sound insulation of non-industrial buildings
IS 2440:1975 Guide for day lighting of buildings
IS 2526:1963 Code of practice for acoustical design of auditoriums and conference halls
IS 3103:1975 Code of practice for industrial ventilation
IS 3362:1977 Code of practice for natural ventilation of residential buildings

Benefits of Concrete floor heating

Reason For Floor Heating: Concrete floor heating is carried out by employing the high thermal mass concerning a concrete slab or floor with preservation of heat in the floor and it performs similar to a large heating panel, to heat the interior space over it and arrange a convenient living surroundings for the occupants.

The hot floor heats the whole space over it and is mostly suitable for finishes like polished concrete floors. Due to its radian output, the concrete floor that has been heated is capable of attaining convenient living conditions at a lower air temperature as compared to normal air heating systems. It is considered as one of the easiest forms of space heating that offers consistent, discreet heat.

The electric constituents or pipes that distribute hot water (called as hydronic systems) are implanted inside the concrete slab or topping screed to heat the concrete slab. Off-peak domestic heating tariffs may also be cost-effective to the homeowner when the energy source remains electricity for either type of system.

Preferably, employing concrete floors for heating is considered as most perfect to the buildings of solid construction where exterior and interior walls also contain a high thermal mass like concrete panel, brick or block walls. These materials, along with the concrete floor function as a heat bank or reservoir which preserve the heat. The method can also be fruitful in buildings of lighter construction along with brick veneer subject to some concern is given to sufficient insulation.

Variations among rough cost and detailed cost

This construction video tutorial sheds light on definition of rough cost and detailed cost and variations among them.

Rough cost estimate plays an important role in construction. If there are huge variations among the rough estimate and the cost of construction that may impact the decision to begin a project. If the rough cost is too high, project may be left devoid of creating its detailed estimate.

Alternatively, if the rough cost is too low then project may begin but once the detailed estimate is made, design and drawings are cancelled because of shortage of fund.

Detailed cost estimates should be made cautiously. These briefly estimate the cost of different items work that set ups the entire project. Detailed estimates are accomplished once the detailed working drawings are made together with specifications. If any error occurs in rough cost estimate, then it will provide great influence in detailed cost estimates.

In this video, example is given for a plinth area having 400 sft. Plinth area belongs to the built up covered area that is computed at floor level of the basement or of any story of building.

The rate is charged as Rs. 400 per square feet and it includes 8% of electricity, 4% of water, 4% of sanitary, 4% Gas etc.

Detailed cost includes earth work, concrete work, brickwork in foundation, DPC (damp proof course), brickwork concerning superstructure, cement plaster, white washing.
