Coal tar modified durable sulfur concrete and preparation method thereof
The invention discloses coal tar modified durable sulfur concrete and a preparation method thereof. Each cubic meter of the coal tar modified durable sulfur concrete comprises the following componentsby mass: 1080 kg of industrial sulfur particles; 600 kg of granular crushed stone; 72 kg of fly ash; 41 kg of granulated blast furnace slag; 342 kg of quartz sand; 29 kg of waste ceramic fine aggregate; 24 kg of waste glass micro powder; 36kg of stone chip powder; 36kg of volcanic ash; 65 kg of rubber particles; and 30kg of glass fiber; wherein the mass of the modifier is 1-5% of the mass of theindustrial sulfur particles; the mass of the thickening agent is 0.1-0.5% of the total mass of the sulfur concrete; and the mass of the coupling agent is 0.3-2% of the mass of the industrial sulfur particles. According to the invention, the durability problem caused by material embrittlement and volume shrinkage due to sulfur solid-phase transformation is solved, the cost problem that the traditional sulfur concrete is generally high in price is solved, and the problems that wastes occupy land and pollute the natural environment are also solved.
本发明公开了一种煤焦油改性的耐久性硫磺混凝土及其制备方法，每立方米各组分质量如下：工业硫磺颗粒1080kg；粒状碎石600kg；粉煤灰72kg；粒化高炉矿渣41kg；石英砂342kg；废弃陶瓷细骨料29kg；废弃玻璃微粉24kg；石屑粉36kg；火山灰36kg；橡胶颗粒65kg；玻璃纤维30kg；改性剂的质量为工业硫磺颗粒质量的1～5％；增稠剂的质量为硫磺混凝土总质量的0.1～0.5％；偶联剂的质量为工业硫磺颗粒质量的0.3～2％。本发明解决了硫磺固相转变导致物料脆化、体积收缩引起的耐久性问题，又解决了传统硫磺混凝土普遍价格高昂的成本问题，同时解决废弃物占用土地和污染自然环境的问题。
