The relative quantity of mixing water, which will bleed from fresh concrete mix can be determined by the test for bleeding of concrete.Test for Bleeding of ConcreteApparatus
Efflorescence in concrete is a whitish coloured powdered deposition of salts on the concrete surface that is formed due to evaporation of water from the concrete. It is caused when water soluble salts are present in the concrete ...
Lime-Soil stabilization is the process of adding lime to the soil to improve its properties like density, bearing capacity etc. Various factors affecting lime-soil stabilization are soil type, lime type, lime content used, compaction, curing period and additives ...
Concrete moisture and vapor tests are conducted to examine the presence and quantity of moisture in concrete floors and slabs. This is because moisture in concrete cause several problems for instance, discoloration, interrupt polymerization of products, and lead to delamination ...
Coarse-grained soil and fine-grained soil are two different types of soil that can be identified based on their texture or ‘feel’ and particle size. It is very crucial to observe the range of particle sizes in soil as it heavily ...
Initial setting time of concrete is the time when cement paste starts hardening while final setting time is the time when cement paste has hardened sufficiently in such a way that 1 mm needle makes an impression on the paste in ...
Blended cement can be defined as uniform mix of ordinary Portland cement (OPC) and blending materials such as silica fumes, fly ash, limestone and slag to enhance its properties for different uses. Blended cement can improve workability, strength, durability and ...
