Aggregates for Concrete

Hydraulic cement concrete is a cement and water paste in which aggregate particles are embedded. Aggregate is granular material such as sand, gravel, crushed stone, blast-furnace slag, and lightweight aggregates that usually occupies approxi-mately 60 to 75% of the volume of concrete. Aggregate properties significantly affect the workability of


Crushed Sand vs. Natural Sand: Make the Right Choice!

Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Crushed sand contains a larger amount of micro- fine particles. This can affect the strength of concrete.


CONCRETE MIX DESIGN USING CRUSHED SAND

The lower the difference between the mean and minimum strengths of the mix lower will be the cement-content required. The factor controlling this difference is termed as quality control. Fineness Modulus : 7.70 The results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.The

Manufacturing of Portland Cement - Cement Concrete

The manufacture of Portland cement is a complex process and done in the following steps: grinding the materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical bonds of


HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

1. Fineness Modulus. It is one of the factors that influence concrete mix design since it controls the proportion of sand in concrete mixture. The overall fineness of sand is given by factor called fineness modulus, and it is found by sieve analysis based on ASTM C 33/ M33 specifications or any other applicable standards.


What Is Fineness Modulus of Sand? - Civil Lead

2. % of weight Passing = (100 – Cumulative % of weight retained) Fineness modulus = (Summation of cumulative % of weight retained up to 150 microns) / 100. Fineness modulus = 240/100. Fineness modulus = 2.4. So, in our case, it is Fine Sand. Also, Read – How to Calculate Cement, Sand and Aggregate Quantity in Concrete?
