Document Type and Number:
WIPO Patent Application WO/2018/101613
Kind Code:
A1
Abstract:
The present invention relates to an autoclaved lightweight concrete (ALC) adhesive composition and an ALC adhesive comprising the same, the ALC adhesive composition comprising: a dry mixture comprising an inorganic binder and an aggregate; and a hydroxyalkyl alkyl cellulose having an alkyl group degree of substitution (DS) of 1.0-1.8 and having a hydroxyalkyl group degree of molar substitution (MS) of 0.2-1.2, wherein the 2 wt% aqueous solution viscosity of the hydroxyalkyl alkyl cellulose is 10,000-100,000 cps when measured by a Brookfield viscometer in a condition of 20°C and 20 rpm. According to the present invention, the ALC adhesive composition comprises a hydroxyalkyl alkyl cellulose having a suitable viscosity and degree of substitution, thereby enabling an ALC adhesive, which has high water retention capacity and high adhesive strength and is applicable to ALC having a high porosity, to be provided.
