    The process of adding silica fume brick brick machine equipment should pay attention to what matters

    Shandong wins Asian machinery specializing in the production of various types of brick, brick machine, brick machine, hollow brick, brick pavement and other equipment of the old brick factory.
             Brick machine in brick making process, sometimes need to add silica fume, but it can improve the performance of silica fume although Frech brick machine, but if used improperly can also cause quality incidents, and thus in use should note the following:
    (1) Due to small particles of silica fume large specific surface area, water demand is high, so when brick machine fume incorporation must obtain good results can be used in combination with superplasticizer.
    There are two in the mixed method and Mixed Method (2) incorporation of silica fume brick machine approach. Because of the mixed method to reduce the amount of cement, therefore the method generally used in concrete, low grade of; Mixed method does not reduce the amount of cement used in concrete high-grade in general.
    (3) brick machine fume dosage should not be too high or too low, the general content of 5% to 10%, the beneficial effect of silica fume in this range to play the best, that is not only the role of silicon powder instead of cement preferably, the excellent performance into full play, and can avoid the adverse effects, such as content greater than 15% have been after, brick machine frost resistance and decreased.
    (4) Due to the consistency of a large fume brick machine brick machine, brick-making machine in the design of concrete slump should be larger than the average 2 ~ 3cm.
    Mixing time (5) silica fume brick machine should extend ordinary concrete than 0.5 ~ 1min, so that the concrete mix more evenly, preventing silica fume in brick machine into the group and cause mass accident.
    (6) brick machine brick machine after mixed with silica fume, the need to strengthen early conservation, prevent plastic shrinkage cracks in the concrete produced.
            Shandong Sheng Machinery Co., Ltd has been committed cement products machinery research and development, production and sales, with advanced equipment, professional and technical skills, and two decades of practical experience, the company has always been at the forefront of research and development center block making machine market development , concerned about the advanced technology at home and abroad, to develop products for the investment needs of different users, there are block making machine, hydraulic tile machine, cement pipe machine, blender, suspended roller machine, wire rod machine equipment. Currently has 19 branch offices and six foreign countries (Nigeria, Tanzania, Algeria, Kenya, Mozambique, Ethiopia) and exported more than 100 countries and regions.
