Good Practices



Some required points to improve the quality of Concrete for stronger & durable Construction,

Constituent of Concrete

Basically the main ingredients of concrete are A) Cement b) Water C) Stone d) Sand Qualities of material are very important for good Concreting.

Compaction of Concrete.
When concrete is placed, the air is trapped inside the concrete. If air is not removed, the air void will weaken the concrete. The voids can lead to the reduction of bond between concrete and reinforcement. It is also the cause of Honeycomb.

As a Result of improper compaction of concrete, approximately 35% of strength is lost.

Curing of Concrete

Curing is the process in which the concrete is protected from loss of moisture and kept within a reasonable temperature range. It should remain protected for sufficient time to become strong and durable. If it is not cured within the first 7 days, the concrete will lose almost 66% of strength.

Preparation of concrete

M-20 Grade of concrete is suitable for RCC construction. (1:1.5:3)Water should be used as per requirement. Excess water should not be used to make the mix more workable
Brick and block masonry
The building material brick is used to make walls, pavements and other elements in masonry construction. Brick is referred to a unit composed of clay, but it is now used to denote any rectangular units laid in mortar.

Block is similar to a rectangular building unit composed of materials, but is usually larger than a brick. The Lightweight bricks are also called lightweight blocks. It is made from expanded clay & aggregate

Mortar

Mortar is a mixture of sand, cement and water that is most often used to build brick, block walls and plaster.

RCC (Reinforcement Concrete Construction)
RCC is Reinforced Cement Concrete in which the structures are reinforced with steel. The steel takes tension and the concrete takes the compression. It is the most widely used construction process, where the improper quality of concrete & concrete cover is the major cause of distress in structure.
