摘要
为了更好地挖掘水泥磨细火山灰稳定碎石的使用潜能,在新掺配比例的基础上,对其抗冻性、耐磨性和抗渗性进行了研究。结果表明:掺加火山灰对于提高混凝土的抗冻性、抗渗性、耐磨性都有促进作用,最佳掺量为15%;用部分火山灰替代水泥,可减少水泥用量,提高经济效益。
For finding more application potential of cement and ground granulated pozzolanic stabilized macadam based on a new composition between cement and pozzolanic, the frost resistance, wear resistance and impermeability were studied. The result shows that pozzolanic has improvement effect for the frost resistance, wear resistance and impermeability of concrete, and the best dosage of pozzolanic is 1 5%, and replacing some cement by pozzolanic can reduce cement dosage and improve economic benefit.
