When water is added to cement an exothermic reaction occurs. During this process, the cement reacts with water to form a gelatinous mass which slowly sets into a hard mass having three dimensional network structure involving$-\mathrm{S}\mathrm{i}-\mathrm{O}-\mathrm{S}\mathrm{i}$– and$-\mathrm{S}\mathrm{i}-\mathrm{O}-\mathrm{A}\mathrm{l}-$chains.
