CEMENTITIOUS TILE ADHESIVES AND METHOD OF APPLYING THE SAME TO A TILE SUBSTRATE

Cement tile adhesives and methods for using them, the adhesives comprising a dry mix of a water-redispersible polymer powder made from a low carboxylation, large particle size water-soluble film-forming vinyl aromatic-diene copolymer latex and a reduced amount of cellulose ether exhibit superior water immersion shear strength and freeze/thaw shear strength.

SELF-REPAIRING CEMENTS

A self-adaptive cement formulation includes cement, water and thermoplastic block-polymer particles. The set cement demonstrates self-healing properties when exposed to methane, and is particularly suited for well-cementing applications. After placement and curing, the self healing properties help maintain zonal isolation should bonding be disrupted between the set cement and the formation or a casing string, should cracks or defects appear in the set-cement matrix, or both.

Preparation method of prefabricated cement block taking super-absorbent resin as filler

The invention discloses a preparation method of a prefabricated cement block taking super-absorbent resin as filler. The preparation method comprises the main process flows of: proportioning cement, water, sand and gravel according to ordinary concrete JGJ55-2000 so as to prepare concrete; and mixing the prepared concrete with the super-absorbent resin according to a certain mass ratio, uniformly mixing the concrete with the super-absorbent resin, shaping and curing, thereby obtaining the prefabricated cement block which takes the and the super-absorbent resin as the filler. The prefabricated cement block prepared by the method has the advantages of light weight and heat and sound insulation, and is expected to play a significant role in the field of construction.
