Claim 13

The method of claim 9 , wherein the method further includes shaping the mixture prior to hardening thereof.

Claim 14

The method of claim 9 , wherein the exothermic reaction is induced in the presence or absence of a hardener.

Claim 15

Claim 18

The method of claim 9 , wherein the mixture further includes adding up to 5 wt % of a synthetic resin.

Claim 19

The method of claim 9 , wherein the mixture further includes adding at least one morganic additive to the mixture.

Claim 20

The method of claim 9 , wherein said forming includes the step of shaping the cementitious product by at least one shaping step selected from the group consisting of molding, spraying and casting.

Claim 21

The method of claim 9 , further comprising adding an air-entraining admixture in an amount of up to 5 wt % of the cementitious product.
