Carbonized enhanced coral reef aggregate and preparation method thereof
The invention discloses a carbonized reinforced coral reef aggregate and a preparation method thereof, and the preparation method comprises the following steps: mixing 100 parts by mass of a carbonized cementing material, 40-70 parts by mass of water and 1-5 parts by mass of cellulose, and fully stirring to obtain slurry; the coral reef aggregate A is placed on a screen and completely soaked in the slurry, the screen is oscillated for a period of time and then taken out, and coral reef aggregate B is obtained; pre-drying the coral reef aggregate B to obtain coral reef aggregate C; and carbonizing and curing the coral reef aggregate C in a carbon dioxide environment to obtain the carbonized enhanced coral reef aggregate. Under the same water-solid ratio, more carbonized cementing materials can permeate into pores of the coral reef aggregate; meanwhile, bubbles in the aggregate are discharged in an oscillation manner, so that pores can be filled with the carbonized cementing material; then, by means of a carbonization curing technology, calcium silicate and other minerals in the carbonized cementing material are carbonized to generate calcium carbonate to fill pores, the water absorption rate is reduced, and the mechanical property of the coral reef aggregate is improved.
本发明公开一种碳化增强珊瑚礁骨料及其制备方法，包括以下步骤：按质量份计，将100份碳化胶凝材料、40～70份水和1～5份纤维素混合，充分搅拌得到浆体；将珊瑚礁骨料A放在筛网上并完全浸泡在浆体中，将筛网振荡一段时间后取出，得到珊瑚礁骨料B；将珊瑚礁骨料B进行预干燥，得到珊瑚礁骨料C；将珊瑚礁骨料C置于二氧化碳环境下碳化养护，得到碳化增强珊瑚礁骨料。本发明在相同水固比下能够使更多的碳化胶凝材料渗透进珊瑚礁骨料的孔隙中；同时利用振荡的方式排出骨料内部的气泡，使孔隙能被碳化胶凝材料填满；之后利用碳化养护技术，使碳化胶凝材料中的硅酸钙等矿物碳化产生碳酸钙填充孔隙，降低吸水率并提升珊瑚礁骨料的力学性能。
