日本应用B—荼硫酸盐超塑化剂,制作高强混凝土已有14年。该外加剂不仅能控制坍落度损失,而且降低水灰比,通常用于泵送混凝土。掺超塑化剂的高强混凝土有许多优点:
Japan has applied B-sulphate superplasticizers for 14 years to produce high-strength concrete. This additive not only controls slump loss but also reduces the water-cement ratio and is commonly used for pumping concrete. High-strength concrete with superplasticizer has many advantages:
