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…
Workability of concrete: – Workability is a property of fresh concrete mixture. Workability means the ease of placement and workable concrete means the concrete which can be placed and can be compacted easily without any segregation. It possesses the property which can be easily placed and mould in to given shape. Significance of workability: –…
