摘要
通过郑西客运专线32m预应力梁C50泵送混凝土双掺粉煤灰和矿渣粉试验,在掺量达36%的情况下,混凝土的强度和耐久性技术参数达到设计要求,明显改善混凝土的综合性能,对较高强度等级的耐久性混凝土的研究和应用具有一定参考价值。
Through the test of fly ash and grounded slag mixing to match C50 pumping concrete in 32m precast beam of Zhengxi passenger dedicated railway, it concluded that technical parameters of concrete strength and durability will meet design request if their volume reach to 36%. It greatly improves concrete comprehensive performance and has some reference value on study and application of high strength durable concrete.
