What is Lightweight Concrete? -Types, Uses and Advantages …
Types of Lightweight Concrete 1. Lightweight Aggregate Concrete. In the early 1950s, the use of lightweight concrete blocks gained acceptance in the UK for load-bearing inner leaf of cavity walls. New types of artificial lightweight aggregates (LWA) paved the way for introducing lightweight concrete (LWC) suitable for structural work.

Procedure For Liter Weight of Clinker The liter weight of clinker is a good measure of burn-ability by calculating the density of the clinker. The size of clinker for liter weight is between 5 & 10 mm. A clinker of density approximately 1100 g/ltr is of normal quality, but below than that is not considered a good…

What is Cement Clinker? Composition, Types & Uses
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
