In general the lower the porosity, the higher the compressive strength. It appears that CH and SP together reduce the pore size or block the pores and as a result the compressive strengths of OPC-FA-CH blended cement are increased. The blocking of pores or reducing pore size may be due the formation of nano size hydration products.
