Abstract: This study systematically investigated the effects of modified ultrafine fly ash, ultrafine silica fume, nano-SiO2, and polycarboxylate superplasticizer on the performance of cement-based grouting materials. Using a five-level orthogonal experimental, the optimal mix ratio was… read more here.
