The different grades of concrete are given as M10, M15, M20, M25, M30, M35 and M40. In the classification of concrete mix, the letter M denote Mix design, and the Numbers represent the predetermined works cube strength of 15cm cube after curing of 28 days in N/mm2. The works cubes strength refers......

Concrete blocks are five or six times larger than bricks, so you might think that setting blocks would be about that much easier. But the blocks are heavier than bricks—about 40 pounds—and require more mortar, so there’s little time or effort saved. Have the blocks delivered as close as possible to......

Workability of concrete is defined as the ease and homogeneity with which a freshly mixed concrete or mortar can be mixed, placed, compacted and finished. Strictly, it is the amount of useful internal work necessary to produce 100% compaction. Another similar term used to describe a freshly prepared concrete is ‘consistency’......

The concrete curing process involves a reaction between Portland cement and water helping on releasing heat from the concrete at a desired and controlled rate. Without curing, moisture is lost too quickly and there isn’t enough water necessary for the crystals to grow, resulting in weaker concrete. Curing of concrete should......
