The main Reason for Vee Bee Test is to Calculate workability and consistency of the Fresh concrete. Vee Bee test provides compatibility and and mobility of the concrete. The test measures the relative effort required to change a mass of concrete from one definite shape to another (i.e., from conical to cylindrical) by means of […]

Compaction factor test is also useful to find out the workability of the fresh concrete. Compaction factor test is more precise way to analyze workability of the concrete. The compacting factor test is designed primarily for use in the laboratory but it can also be used in the field. It is particularly useful for concrete

What is Heat of Hydration of Cement: – When Portland cement is mixed with water, heat is liberated. This heat is called the heat of hydration, the result of the exothermic chemical reaction between cement and water. Significance: – The heat generated by the cement’s hydration raises the temperature of concrete. These temperature rises cause
