TH26750A - Mixture for lightweight building materials And methods for the preparation of lightweight building materials. - Google Patents

Abstract

Methods for the preparation of lightweight building materials in the form of sheets The Actuess Gallery consists of (A) cement, rice husk ash with a weight of 2.5% to 7% carbon by weight (C), fibrous materials such as pulp that have been transformed and (D) Homogenizing agents such as water soluble polymers Each in a particular proportion And will be molded by It is then sent to curing and drying in a steamed atmosphere. Without It is necessary to use an expensive hydrothermal method.
