Apr 28, Concrete is a remarkable product, having been used for thousands of years as a reliable and durable building material for a countless amount of structur In its most basic form, concrete is a simple combination of cement, water and granular material (sand and/or rock).
May 22, Concrete mix design is the process of selecting the ingredients for a concrete mixture and deciding on their proportions When designing a concrete mix, you should always consider the desired strength, durability, and workability of the concrete for the project in question Calculating Concrete.
A material other than water, aggregates, or cement that is used as an ingredient of concrete or mortar to control setting and early hardening, workability, or to provide additional cementing properti Admixtures are generally used to alter the properties of concrete (such as increased workability or reduced water content, acceleration or retardation of setting time.
to a concrete with a slump of 3 to 4 inches (75 to 100 mm) will produce a concrete with a slump of about 8 inches (200 mm) Some HRWRs may cause a higher rate of slump loss with time and concrete may revert to its original slump in 30 to 45 minut In some cases, HRWRs may be aded at the jobsite in a controlled man-ner.
Functions of Cement Ingredients The main features of these cement ingredients along with their functions and usefulness or harmfulness are given below: Lime: Lime is calcium oxide or calcium hydroxide Presence of lime in a sufficient quantity is required to form silicates and aluminates of calcium.
