QUALITY CONTROL IN CONCRETE CONSTRUCTION WORK - CivilBlog.Org

This stage of quality control consists of two steps. 1. Checking of specification requirements regarding excavation, forms, reinforcement and embedded fixtures etc. 2. Control test on concrete ingredients (i.e. on cement, aggregate & water) Cement Quality of cement is ascertained by making compressive strength tests on cement cubes. However for effective control cement: 1. Should be tested initially once for each source and subsequently once for every two months 2. Should be protected from moist

Quality control in Construction – it all starts with concrete

The construction quality control system Looking in more detail at the way the concrete quality control system works, it can be understood that the discrepancy of concretes makes it possible to minimise the consumption of cement, and ultimately allows the production of concrete to run more economically (Troxell, Davis & Kelly, 1965).

Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...
