specific Embodiment 1
[0030] Specific embodiment 1: prepare raw material according to the following ratio: 710 parts of ordinary Portland cement; Average particle diameter 0.30um, Sio 2 185 parts of silicon powder with a content ≥ 92%; 1150 parts of quartz sand with a particle size of 0.16-1.25mm; 14 parts of superplasticizer; 175 parts of water; 110 parts of copper-plated steel fiber with a diameter of 0.18-0.25mm and a length of 11-15mm .
[0031] After the above-mentioned raw materials are equipped, prepare according to the following steps:
[0032] ① Add the copper-plated steel fiber and quartz sand with limited formula into the mixer and stir for 1 to 1.5 minutes until uniform to make spare materials;
[0033] ②Add the cement and silica fume specified in the formula and 30% of the formula water to the spare materials and continue to stir for 0.5-1.0 minutes until uniform and ready for use;
[0034] ③ Mix the high-efficiency water reducer and the remaining water in the above formula evenly, t...
