What can you add to Portland cement to make it sulphate resistant?
The sulphate resistant cement is made with low C3A content is found to be effective.Such cement with low C3A and comparitively low C4AF content is known as sulphate resisting cement.This cement has a high silicate content.The specification generally limits the C3A content to 5 percent.
What is the meaning of electrical properties?
It depends upon the context! It is a group of properties distinct from those which are mechanical, magnetic, visual, optical, physical, etc of an object, component or system. It would mean specific sets of properties depending upon the context; electronic components, biological tissue, etc. A poor question, requiring the very general and non-specific response above.
What is Pozzolana Portland Cement?
Portland pozzolana cement is produced either by grinding together portland cement clinkers and pozzolana with addition of gypsum. The pozzolana constituents shall not be less than 10% and not more than 25 % by weight. The homogenity of mix shall be guaranteed within + or - 3 % within the same consignment.

Is concrete hardening an example of chemical or physical change?
Concrete hardening is an example of a chemical change. When water is added to the cement mixture, a chemical reaction occurs between the water and the cement particles, resulting in a new substance with different properties than the original components.

What are the chemical and physical properties of cement?
Three varieties of the strength of cement are measured – compressive, tensile, and flexural. Several factors affect the strength, such as water-cement ratio, cement-fine aggregate ratio, curing conditions, size and shape of a specimen, the manner of molding and mixing, loading conditions, and age. I hope it will assist you.
What are the insoluble residue in cement?
The insoluble residue in cement mainly consists of unhydrated cement particles, minerals, and impurities. These residues can affect the performance and properties of the cement, such as strength development and durability. Proper quality control measures are important to ensure optimal composition and properties of cement.
Properties that describe the appearance of matter are known as?

Is mixing cement a chemical or physical change?
Actually both physical and chemical changes are happening during cement mixing.
Why glass ionomer cement not mixed on glass slab?
Glass ionomer cement should not be mixed on a glass slab because the ions present in the cement can react with the glass slab, leading to contamination and affecting the setting reaction of the cement. This can compromise the physical properties and performance of the cement. It is recommended to use a disposable mixing pad or a mixing paper to prevent any unwanted reactions and ensure the proper setting of the glass ionomer cement.
