Modified CRT glass and ultra-high performance concrete
The invention discloses CRT glass reinforced ultra-high performance concrete and a preparation method thereof.The modification process of modified CRT glass comprises the following steps that CRT glass and a modification liquid material are evenly mixed according to the mass ratio of 100: (21.2-24.4) and then stacked, leakage liquid at the bottom of a CRT glass stack is collected and then cyclically poured to the top of the CRT glass stack, and aging is conducted for 4-6 days; the pH value of the modified liquid material is 9.2-9.8, the raw materials of the modified liquid material comprise water, cement and slaked lime, the modified CRT glass more easily participates in a hydration reaction in concrete, the bonding interface of the modified CRT glass and a bonding phase is deeper, the bonding strength is higher, and inhibition of addition of the glass on the hydration reaction of the concrete and reduction of the strength are weakened; the modified CRT glass is added into the ultra-high-performance concrete, so that the ultra-high-performance concrete is good in flowability and low in mechanical property degradation.
本申请公开了一种CRT玻璃增强的超高性能混凝土及其制备方法，改性CRT玻璃的改性过程包括以下步骤：将CRT玻璃与改性液料按100：（21.2~24.4）的质量配比拌合均匀后堆放，CRT玻璃堆底部渗漏液收集后循环淋倒于CRT玻璃堆顶部，陈化4~6天；改性液料pH为9.2~9.8，其原料包括水、水泥、熟石灰，改性CRT玻璃更易参与混凝土中的水化反应，与黏结相结合界面更为深入结合强度更高，减弱玻璃加入对混凝土水化反应的抑制以及强度降低；超高性能混凝土加入本申请的改性CRT玻璃，超高性能混凝土的流动性好，力学性能衰减少。
