NON-FIRED BUILDING BLOCKS AND THE PRODUCTION PROCESS OF THESE NON-FIRED BUILDING BLOCKS

Abstract

The invention relates to a nonfired building block produced by shaping a self-curing composite material without firing, wherein this self-curing composite material consists of: basic materials including cement, sand, fly ash, synthetic fibers, water; and an additive made from ground cellulose material (e.g., rice husk) and acrylic-based polymer, referred to as a polymer-cellulose additive, wherein this polymer-cellulose additive is produced by mixing ground cellulose material with liquid acrylic-based polymer such that the particles of ground cellulose material are wetted and coated by an acrylic-based polymer film. This creates a self-curing composite material with reduced water absorption and capillary permeability for the nonfired building block. The invention also relates to a nonfired composite material and a process for producing a nonfired composite material with a similar material composition as described above.
