Cement has not a melting and boiling point; after heating cement is thermally decomposed.
To increase the melting point of aluminium, (and treating this as a philosophical question), then hardening the 'crystal matrix' may be one approach. Surface hardening by work hardening, or perhaps by inserting nitrogen ions into the surface as is used in metal(ferrous) hardening.
Sedimentary melting cooling and hardening Metamorphic
Pumice and Basalt
Low--it's easier for it to harden when it's not flowing. This is also why cement mixers spin to keep the cement from hardening.

It is not rain forced but re-inforced cement concrete. It means the concrete after setting and hardening.
both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change both, because the ingredients are undergoing both physical and chemical changes such as: Butter melting= physical change Egg whites hardening= chemical change
Cement when mixed with sufficient quantity of water,the compounds present in cement reacts with water to form a cementitious crystalline structure that adheres to the sand and aggregates.This helps in binding the mass together and increases its strength till it becomes very hard.This is called hardening of cement.

no..it will be in liquid state and after it reaches its settling time, concrete starts hardening and finally to solid state...
