土建施工中传统的混凝土搅拌方法一般是先将水泥、砂石粒料等干料拌合均匀后,再加规定比例的水搅拌而成(俗称干匀搅拌法)。日本土建工程师发明了一种新型的混凝土搅拌先进方法,称为“水泥裹砂搅拌法”(Sand Envdoped With Cecnent),简称SEC法。这种方法步骤是:1.先将砂子拌水,使砂石含水量在15～25%;2.将水泥投在湿砂中

The traditional method of concrete mixing in civil construction is generally to mix the dry materials such as cement and gravel aggregates together, and then add a prescribed proportion of water to stir (commonly known as dry mixing method). Japanese civil engineering engineers invented a new advanced method of concrete mixing, known as “Sand Envdoped With Cecnent” (SEC). The steps of this method are: 1. Mix the sand first to make the sand water content 15 to 25%; 2. Put the cement in the wet sand.
