Abstract

The invention relates to a processing method of a light vesuvianite-imitated paving block. The invention provides the processing method of the light vesuvianite-imitated paving block which is high in reliability and strong in replicability on the premise that the product strength is met and the characteristics of natural vesuvianite are embodied at the same time. Porous matrix slurry is used as a raw material, the porous matrix slurry is poured into a mold and solidified, and the porous matrix slurry is prepared from, by mass, 60-95 parts of cement, 5-50 parts of mineral micro powder, 0.5-2.5 parts of plasticizer and 27-41 parts of water. After the porous matrix slurry is prepared, 100-1200 g/m < 3 > of a foam stabilizer, 0.4-1.5 g/m < 3 > of a pore adjusting agent and a foaming agent are added into the porous matrix slurry according to the volume-mass ratio, and the adding amount of the foaming agent is calculated and quantified according to the designed dry apparent density of the porous matrix; after the porous matrix slurry is condensed and hardened, the porous matrix of the pelelith-imitating decorative material is formed, so that pores with different proportions and different pore sizes can be stably dispersed in the porous matrix of the pelelith-imitating decorative material.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, and in particular relates to a processing method of imitation volcanic rock pavement materials. Background technique [0002] In order to form the simulation effect of volcanic rock in the porous matrix, it is necessary to make the solidified material have bubbles of different sizes. The applicant's preliminary research and development results include "CN110394880A, imitation volcanic slag decorative sheet, imitation volcanic slag veneer decorative block and its processing method", and "Preparation and performance research of lightweight porous concrete with imitation volcanic slag decoration effect, "Concrete and Cement Products", 2020-6". [0003] The porosity of the volcanic slag-like lightweight thermal insulation composite block produced by the former is irregular in shape, oblong, and of different sizes. According to statistics, the porosity is 32-42%, and the porosit...
