Specific Gravity of Cement - Detailed

If the cement has exposed to extreme moisture content then, the specific gravity of cement will differ because of the moisture content present in the pores. Every material has solid particles and pores which may contain water in it. Normally our nominal mix design is based on the value of specific gravity of cement as 3.15. The value will

What is the Difference Between OPC and PPC

OPC Cement or Ordinary Portland Cement (OPC) is manufactured by grinding a mixture of limestone and other raw materials like argillaceous, calcareous, gypsum to a powder.This cement is available in three types of grades, such as OPC 33 grade, OPC 43 grade and OPC 53 grade. OPC is the most commonly used cement in the world.

Ordinary Portland Cement - Tests, Properties,

Cement can be defined as the bonding material having cohesive & adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly. Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in

Bulk Density - an overview | ScienceDirect Topics

The bulk density of the powder is measured using a cylinder of known volume placed under the dry flow test funnel as shown in Fig. 15.7.The powder is leveled off after filling the cylinder (taking care not to tamp it and cause settling) and weighed. The weight of the powder is then divided by the volume of the cylinder to calculate bulk density.
