Plain Cement Concrete (P.C.C) has very low tensile strength. To improve the tensile strength of concrete, some sort of reinforcement is needed which can take up the tensile stresses developed in the structure. The most common type of reinforcement is […]
In this post, we are going to explain how to do quantity analysis for Materials, i.e quantities of cement and sand required for Cement Plaster. Plaster is a building material used for the protective or decorative coating of walls and
Flow Test Flow Test is a laboratory test, which gives an indication of the quality of concrete with respect to consistency, cohesiveness and the proneness to segregation. In this test, a standard mass of concrete is subjected to jolting. The
The compacting factor test is designed primarily for use in the laboratory but it can also be used in the field. It is more precise and sensitive than the slump test and is particularly useful for concrete mixes of very
Introduction Very recently a new apparatus called “K-Slump Tester” has been devised. It can be used to measure the slump directly in one minute after the tester is inserted in the fresh concrete to the level of the floater disc.
Introduction The quality of concrete satisfying the above requirements is termed as workable concrete. The word “workability” or workable concrete signifies much wider and deeper meaning than the other terminology “consistency” often used loosely for workability. Consistency is a general
Introduction The slump test is the most commonly used method of measuring the consistency of concrete which can be employed either in a laboratory or at the site of work. It is not a suitable method for very wet or
Introduction By Definition, Workability means the property of the concrete, which measures how easily a concrete can be mixed, transported, placed, compacted and finished. In other words, it indicates the degree of plasticity. The word ‘workability’ assumes the full significance
