Abstract:
To that end, this invention proposes a vertical thermal-acoustic enclosure, constructed from building blocks, in which the joint between blocks is a synthetic cement putty, said enclosure being characterized by the fact that synthetic cement putty has the following mechanical properties: - Hardness between 10 and 50 Shore A; - Tensile strength between 0.1 and 3 MPa Characteristics that give the closing acoustic properties that significantly improve its noise performance compared to walls built with other known putty fillers.

Abstract:
A molded cured product obtained from a kneaded material using hydraulic powdery material, latent hydraulic fine powder, compounding water and if necessary, fine aggregate is hot aged under a specific condition so that silicic acid anion of at least a trimer is formed in calcium silicate hydrate formed in the texture of this molded cured product. This molded cured product has a compressive strength of at least 1,000 kgf/cm and a bending strength of at least 150 kgf/cm , and can suitably improve strength characteristics, particularly the bending strength as characterising drawback of cement type products, without using a specific reinforcing material and a compounding material such as a fiber, or even when these reinforcing material and compounding material are used, by drastically reducing their quantities. Accordingly, the present invention can advantageously provide a unique and novel cement type product. Incidentally, beautiful mortar or concrete products by glost firing, which has not been able to be practised due to unavoidable drop of strength characteristics, can be produced and provided as products having desirable bending strength, compressive strength and elastic modulus.
