This method of concrete mix design consist of following 11 steps. Design specification. Testing of materials. Calculating target strength for mix proportioning. Selecting water/cement ratio. Calculating water content. Calculating cement content. Finding out volume proportions for Coarse aggregate & fine aggregate.

Cost - The simple rule of demand and supply makes river sand more expensive than crushed sand. Many still prefer making their homes with river sand where procurement is not the issue. However, river sand being organic is not an ideal construction material of choice. Performance - Crushed sand is made from the debris of construction …

Generally, crushed stones of rocks are used as conventional coarse aggregates whereas Natural River sand is used as fine aggregate, both are available naturally . As concrete is the 2nd most usable material behind water by humans so due to their higher quantity usage leading to depletion of this naturally available material at …

This comparison showed that the flexural strength could be maintained by totally replacing the natural sand in the concrete with crushed sand and could be even slightly improved with the well-graded crushed sand (ratios of 1.08 and 0.96 for the equivalent mixes EM-30 and EM-40, respectively and 1.11 and 1.07 for the modified …

The hollow load-bearing concrete block of standard 400 mm x 200 mm x 200 mm size will weigh betw-een 17 kg and 26 kg when made with normal weight aggregates. Normal weight units are made with such aggregates as sand, crushed stones and air-cooled slag. (Continued. on third cover) IS 2185 (Part 1) :2005.

Most of the states in our country have banned sand quarrying from the river beds, causing a scarcity of natural river sand for the construction sector. Manufacture sand (M-sand) is one of the alternate solutions to replace the river sand (R-sand) in concrete. The main aim of the present study is to evaluate the durability parameters of concrete …

Historically sand washing or wet classification [] has been applied to remove the fine filler Footnote 1 particles of poor quality, e.g., flaky or of high specific surface area due to weathering and clay alteration, or in excess amounts [].Such particles are unwanted in concrete since they impair the workability and increase the water demand [4, 8, 19, …

Although the compressive strength of natural sand concrete was not significantly affected by the incorporation of VFS, crushed stone sand concrete indicated an increase in strength.
