Formula design for novel fly-ash-based insulating dry powder

Abstract

The invention relates to the technical field of construction energy saving insulating materials, and discloses a formula design for a novel type of fly-ash-based insulating dry powder. The designed formula comprises the following components: (1) fly ash; (2) a strengthening material; (3) a calcifying agent; (4) an insulating filling material; and (5) a thickener. Designed with a special formula, the insulating dry powder has advantages of simple components and simple production processes. Fly ash with a low cost is adopted as a base material, and the inorganic insulating filling material is added to the formula, such that the insulating dry powder is environment protecting, energy saving, and is highly efficient. After the dry powder product is mixed with water, a high-quality insulating mortar can be obtained. The insulating mortar has a density of 1.7 to 1.8g / cm<3>, a compressive strength of 10Mpa after solidification, and a heat transmission coefficient of 0.025w / (m.k) after solidification.

Description

technical field [0001] The invention relates to a formula design of a novel fly ash-based thermal insulation dry powder, which belongs to the technical field of building energy-saving thermal insulation materials. Background technique [0002] Dry powder mortar refers to a granular or powdery mixture of aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) that have been dried and screened in a certain proportion. , transported to the construction site in bags or in bulk, and can be used directly after mixing with water. Also known as mortar dry powder, dry mix, dry mix powder, some construction adhesives also belong to this category. Dry powder mortar plays the role of bonding, padding, protection and decoration in thin layers in the construction industry, and is widely used in construction and decoration engineering. [0003] Traditional dry powder is generally used for bonding and decoration, and its functio...

Problems solved by technology

Over a thousand types of dry powder mortars have been developed abroad, but in my country there are less than a hundred types. Therefore, the phenomenon that the mortar does not match and does not meet the functions appears in use, which has a very negative impact on the promotion and use of mortar.
