What is cement formula?

4CaOAl2O3Fe2O3 = calcium alumino ferrite. C-S-H. Calcium silicate hydrate, a colloidal and mostly amorphous gel with a variable composition; this is the major hydration product of Portland cement, constituting approximately 70 percent of the paste, and is the phase providing most of the strength and binding.

Can I use mortar to fill a hole?

Can you use washing up liquid in mortar?

Washing-up liquid Washing up liquid is commonly used as a plasticiser in cement mortar.

What happens if you put too much cement in mortar?

Since major force transfer in a concrete/mortar matrix is from sand-sand interaction, excess cement will turn the mortar very brittle since cement particles cannot transfer normal contact force – they are good at providing shear strength.

Can I use sharp sand for mortar?

Mortar is typically used for bricklaying and pointing. Sharp sand is ideal for mixing with other sands to increase the strength of the mortar and for when it needs to be less workable. A key benefit of adding sharp sand to the mortar mix is that it can prevent cracking during the drying process.
