Coarse Aggregate Classification Of Coarse Aggregate 8

Jul 08, 2021 Aggregate is the inert granular material that is used in the concrete as the filler material and provides volume to the concrete. There are two types of aggregates naming fine aggregate and coarse aggregate. We are discussing coarse aggregate in this article. 1. Introduction

Heavyweight Aggregates For Heavyweight Concrete Production

Heavyweight aggregates as it can be seen from the name is an aggregate that posses relatively high density and it is fundamental in a situation that high density concrete is necessary. Generally, aggregates with specific gravity of 2400 Kgm 3 and higher are considered to be heavyweight. The concrete density that can be obtained based on the ...
