2015-10-2 Department of Civil Technology Written By: Ahmed Zakaria 20 Making Blend of Aggregate 3/4 3/8. In concrete design an engineer should make at least 5 blend. To make blend, make the ratio of 3/4 3/8 aggregate by dividing them into 100%. For Example, take aggregate 3/4=40%, aggregate 3/8=60% which equals to 100% on adding ratio's Similarly calculate 3/4 @ 60% 3/8 @ 40% unless your results match the specification table try five different ratios. In this report

Manufactured sand differs from natural sea and river dredged sand in its physical and mineralogical properties. These can be both beneficial and detrimental to the fresh and hardened properties of concrete. This paper presents the results of a laboratory study in which manufactured sand produced in an industry sized crushing plant was characterised with respect to its physical and ...
