4.   SAMPLING OF REINFORCING STEEL:

Steel plays a vital role in the construction of humongous structures nowadays. It may be used as reinforcement in concrete or as a structural member itself. The correct method of sampling is of high importance to ensure the true characteristics of the

Method of Sampling of Construction Materials - Based on Indian Standards [Part 1]

Author: Shubham Raj

The present article gives an overview of the method of sampling of commonly used construction materials, based on relevant Indian Standards published by the Bureau of Indian Standards (BIS). The article covers the sampling of cement, aggregates, bricks, reinforcing steel, concrete, wood and timber.

1.   SAMPLING OF CEMENT:

Cement is one of the most important ingredients of concrete which binds the aggregates and influences the strength and durability to a great extent.

Suitability of Recycled Aggregate as a Replacement for Natural Aggregate in Construction

Authors: D.D. Tripura; Shubham Raj; Sher Mohammad; Rima Das

Synopsis: This study investigates the effect of recycled coarse aggregate (RCA) as replacement of natural coarse aggregate on the strength properties of concrete. The investigation was carried out by conducting unconfined compressive strength (UCS) test, indirect tensile strength (ITS) test, flexural strength test and bond strength test on five concrete mixtures using 0%, 25%, 50%, 75% and 100% by weight of RCA as replacement of natural coarse aggregate. The test samples were prepared with a target strength of 40 MPa (6000 psi). Water-cement ratio (w/c) and slump were adopted as 0.40 and 100 mm (4.0 in.) respectively.
