Abstract

The invention discloses solid sulfur ash masonry mortar. The solid sulfur ash masonry mortar is characterized by comprising the following components in parts by weight: 200 to 490 parts of solid sulfur ash, 30 to 100 parts of lime, 410 to 770 parts of sand, and 0.1 to 0.5 part of water holding thickener. The solid sulfur ash is used as a main raw material for preparing the masonry mortar, so that solid sulfur ash slag discharged by a circulating fluidized bed can be fully utilized, waste of land resources and pollution to the natural environment when the solid sulfur ash is stacked in open air are reduced, meanwhile, the contractility of the masonry mortar is reduced, the water holding property of the masonry mortar is improved, the cost of the masonry mortar is reduced, and the practicability is strong.

Description

technical field [0001] The invention belongs to a mortar composition and relates to a sulfur-fixing ash masonry mortar. The sulfur-fixing ash masonry mortar of the invention is suitable for use as building materials. Background technique [0002] Sulfur-fixing ash refers to the fly ash and ash collected after the sulfur substance contained in raw coal is mixed with a sulfur-fixing agent (usually limestone) in a certain proportion and then burned in a circulating fluidized bed boiler to fix sulfur at 850-900°C. Fluidized bed sulfur-fixed ash is a kind of coal-burning ash with special properties, because the temperature of coal combustion does not reach the temperature when the liquid phase appears, compared with common fly ash, sulfur-fixed ash is usually loose and porous , so the water requirement of standard consistency is much higher than that of fly ash. Due to the addition of calcareous sulfur-fixing components, the sulfur-fixing ash has obvious self-hardening properti...
