Abstract

The invention relates to the technical field of preparation of gel materials and building structural members, in particular to active dry powder, a decorative plate, a prefabricated part and a preparation method of the prefabricated part. The active dry powder is prepared from the following components in parts by weight: 15 to 45 parts of cementing powder, 8 to 25 parts of a composite exciting agent, 1 to 5 parts of quick lime, 1 to 6 parts of plant ash and an aggregate; the composite exciting agent is prepared from water glass and alkali carbonate. According to the active dry powder, the plant ash is used as an exciting raw material, and a silicon and aluminum element-containing component of the plant ash is an active component; potassium carbonate in the plant ash and the composite exciting agent achieve a synergistic effect to enhance the exciting effect; insolubles of the plant ash can be used as filler; by the adding of the quick lime, the quick lime is used as a raw material for polymerization reaction, and also achieve a catalysis effect of promoting the reaction. An experiment shows that by the use of the quick lime and the plant ash, hardening of a cementing material is accelerated, and the activity and the early strength of the cementing material are greatly improved; particularly, the prepared prefabricated part is high in compactness, high in waterproofingness and high in strength; meanwhile, the phenomenon of dry shrinkage is obviously improved.

Description

technical field [0001] The invention relates to the technical field of preparation of cementitious materials and building components, in particular to a decorative board. Background technique [0002] Inorganic polymer cementitious material is a new type of cementitious material that has received great attention in the fields of construction engineering and environmental engineering at home and abroad in recent years. It uses industrial waste residue as the main raw material and has the advantages of low price, abundant reserves, low energy consumption, and excellent preparation technology. It is a new type of green and energy-saving building material with broad development prospects. At present, inorganic polymer cementitious materials are basically still in the stage of experimental research and application exploration in my country, mainly focusing on material preparation, microstructure and research on the influence of concrete mechanical properties, corrosion resistance...
