Abstract

The invention discloses an inorganic thermal insulation light mortar, the mortar is mainly composed of a raw material and water in the following percentage by mass: the raw material is composed of 45-55% of lightweight aggregate, 15-20% of hydraulic material, 12-18% of air-setting material, 7-10% of active stuffing and 5-8% of additives; and the mass ratio of the water to the raw material is 0.15-0.25. The mortar in the invention is selected based on a principle of combining a hydraulic cementing material with an air-setting cementing material to satisfy material strength development and application quality demand and effect under a wall body environment condition; a non-gravity gasification suspension stirring technique is applied for achieving an expected stirring effect of generating no damage on a light thermal insulation material; and a one-time continuous jetting construction technique is utilized for not only solving the air bubbling and cracking problems of a wall body, but also greatly improving the construction quality, thermal insulation effect and construction efficiency.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an inorganic thermal insulation lightweight mortar and a construction method thereof. Background technique [0002] Inorganic thermal insulation materials are widely used in developed countries, mainly because of their good ecological and environmental protection, sustainable recycling and super economic and practical value. my country's resources are extremely limited and the situation of ecological environmental protection is becoming increasingly severe. The country is so large Large-scale building insulation and energy-saving projects need to consume a lot of insulation materials. If too much reliance is placed on organic insulation materials, if the insulation layer is discarded due to technical reasons, fire or natural aging after a few years, it will definitely cause serious pollution to the environment and cause serious damage to the environment. Let us pay a huge economic...
