Problems solved by technology

However, the density of lightweight aggregate is small. Under high fluidity, the mixture is prone to segregation and bleeding, which makes the lightweight aggregate float and drift, resulting in difficulty in pumping, uneven density distribution of hardened concrete, and uneven distribution of building strength. The problem of equalization seriously affects the construction progress and building quality

Abstract

The invention discloses a light aggregate self-leveling material, a preparation method and a construction method. Coal gangue powder, gypsum and the like are used as raw materials; prefabricated particles are obtained through formation of polyaniline and decomposition of hydrogen peroxide; tetraethoxysilane, trimethyl borate and aluminum nitrate are taken as raw materials to prepare aerogel; perlite, floating beads, prefabricated particles and aerogel are used as raw materials to prepare light aggregate, and finally gypsum, cement, mineral powder, the light aggregate, a defoaming agent, methylcellulose, a thickening time control agent, a water reducer and a waterproof agent are fully mixed to obtain the light aggregate self-leveling material, which is light, environmentally friendly, goodin construction performance and easy to construct.

Description

technical field [0001] The invention relates to a self-leveling material, in particular to a lightweight aggregate self-leveling material, a preparation method and a construction method. It belongs to the technical field of building materials or related application fields. Background technique [0002] Self-leveling is a ground construction technology, usually composed of cement-based or gypsum-based cementitious materials, fine aggregates, fillers, and additives. The unevenness of the ground flows along the trend, and the ground is automatically leveled. [0003] Traditional cement or gypsum self-leveling does not have excellent thermal insulation and heat insulation effects. However, energy saving and environmental protection are one of the basic national policies of our country. Therefore, the country is promoting the requirements for environmental protection and energy saving of buildings. Combined with the construction requirements of floor heating or partition walls,...
