Testing plays an important role in controlling the quality of cement concrete work. Systematic testing of raw materials, fresh concrete and hardened concrete, is an inseparable part of any quality control programme for concrete. This helps achieve a higher efficiency of the materials used and greater assurance of the performance of the concrete, in regard to workability, strength and durability. The test methods used should be simple, direct and convenient to apply. This standard was prepared with this objective in view.
The Bureau of Indian Standards (BIS), has come out with the draft Indian standards for hardened concrete. The BIS has asked the stakeholders to examine the drafts and forward their views stating any difficulties which are likely to experience in business or profession if this is finally adopted as National Standard.
