Abstract

The invention provides full-machine-made sand wet-mixed mortar, which comprises the following components in parts by weight: 180-200 parts of cement, 18-22 parts of fly ash, 8-12 parts of limestone powder, 8-12 parts of semi-hydrated gypsum, 18-22 parts of vitrified micro beads, 180-220 parts of water, 3-7 parts of an additive, 20-30 parts of activated sludge and 1200-1600 parts of machine-made sand, wherein the water is from starch slurry waste liquid with the starch content of 8-12%, and the additive comprises 3% of amylase, 5% of latex powder, 2% of lauryl sodium sulfate and 90% of sodium gluconate. The invention further provides a processing method of the wet-mixed mortar, wherein starch production wastewater and activated sludge generated in urban life are utilized, so that secondarypollution of the starch industry and the activated sludge to the environment is avoided, and a large amount of waste materials can be consumed while the production cost is reduced. According to the invention, additives used in the production process are simple in component, can be purchased in the market, do not affect normal production of enterprises and can be popularized in wet-mixed mortar enterprises; and a full-machine-made sand formula is used, so that river ecology is not damaged.

Description

technical field [0001] The invention relates to the technical field of wet-mixed mortar processing, in particular to a whole machine-made sand wet-mixed mortar and a processing method thereof. Background technique [0002] Wet-mixed mortar refers to cementitious material, fine aggregate, admixture, water and various components determined according to performance. According to a certain proportion, after being measured and mixed in the mixing station, it is transported to the place of use by a mixer truck. Store the mortar mixture in a special container and use it within the specified time. The working principle of wet-mixed mortar is similar to commercial wet-mixed mortar, and the commercial wet-mixed mortar mixing station can simultaneously produce wet-mixed mortar. [0003] Fine aggregate mainly includes machine-made sand and river sand, among which river sand comes from river mining, and the mining process will inevitably lead to the destruction of river ecology, which i...
