Artificial agglomerated stone waste residue-based cement mortar reinforcing agent and preparation method thereof
The invention discloses an artificial agglomerated stone waste residue-based cement mortar reinforcing agent and a preparation method thereof. The reinforcing agent comprises the following components:artificial agglomerated stone waste residues, a polymer emulsion and a water reducing agent. The preparation method comprises the following steps: drying and crushing the artificial agglomerated stone waste residue, modifying the artificial agglomerated stone waste residue powder by using the polymer emulsion, and finally mixing the artificial agglomerated stone waste residue powder or the polymer emulsion modified waste residue powder with the water reducing agent to obtain the artificial agglomerated stone waste residue-based cement mortar reinforcing agent. The cement mortar reinforcing agent provided by the invention can establish strong interface interaction with cement particles and hydrated products thereof, effectively reduce the porosity and the number of cracks in an interface transition region, greatly improve the compressive strength and the bending strength of cement mortar, reduce the dosage of a water reducing agent under the condition of ensuring the strength, and is high in economic benefit. The preparation method is simple and has an extremely wide market application prospect.
本发明公开了一种人造岗石废渣基水泥砂浆增强剂及其制备方法，所述增强剂组分包括人造岗石废渣、聚合物乳液、减水剂。其制备方法为：首先对人造岗石废渣进行烘干和粉碎处理，然后用聚合物乳液对人造岗石废渣粉体进行改性，最后将人造岗石废渣粉体或聚合物乳液改性废渣粉体与减水剂混合即可得到人造岗石废渣基水泥砂浆增强剂。本发明提供的水泥砂浆增强剂可与水泥颗粒及其水化产物之间建立强的界面相互作用，有效减少界面过渡区的孔隙率和裂缝数量，大幅度提高水泥砂浆的抗压强度和抗弯折强度，还可以在保证强度条件下降低减水剂用量，经济效益高，制备方法简单，具有极为广阔的市场应用前景。
