Concrete for power transmission line construction
The invention discloses concrete for power transmission line construction. The concrete comprises the following components in parts by weight: 508-700 parts of sulphoaluminate cement; 1900-2100 partsof aggregate; 1-5 parts of an early strength component; 15-20 parts of a polycarboxylate superplasticizer; 1-5 parts of modified polypropylene fiber; 250-300 parts of water. The concrete for power transmission line construction provided by the invention is high in early-stage pressure resistance and short in maintenance time, the construction time is greatly shortened, and the construction cost isreduced.
本发明公开了一种输电线路施工用混凝土，混凝土以重量份数计包括以下组分：硫铝酸盐水泥508～700份；骨料1900～2100份；早强组分1～5份；聚羧酸系高效减水剂15～20份；改性聚丙烯纤维1～5份；水250～300份。本发明提供的输电线路施工用混凝土，该混凝土的早期抗压能力强，且养护时间短，大大缩短了施工时间，降低施工成本。
