Concrete extrusion wallboard and preparation method thereof
The invention relates to a concrete extrusion wallboard and a preparation method thereof, and relates to the technical field of building materials. The preparation method of the concrete extrusion wallboard comprises the following steps that portland cement, sulphate aluminium cement, gypsum, aggregate and water are mixed and stirred to prepare a concrete blank; and vibration extrusion is conducted on the concrete blank to prepare the concrete extrusion wallboard. The technological parameters of vibration extrusion comprise the vibration amplitude of vibration of 0.9 mm to 1.1 mm, and the mainvibration frequency of 45Hz to 55Hz; and the spiral spacing of a reamer of 65 mm to 80 mm, the spiral length of 290 mm to 310 mm, the taper of the spiral bottom diameter of 35 degrees to 45 degrees,and the rotating speed of the reamer of 210r/min to 230r/min; And the assisting frequency of the advancing speed of the concrete blank is controlled to be 35Hz to 39Hz. The prepared concrete extrusionwallboard is small in surface density, large in compactness, high in strength, large in drying shrinkage value, small in thermal expansion and cold contraction coefficient and small in cracking rateafter installation.
本发明涉及一种混凝土挤压墙板及其制备方法，涉及建筑材料技术领域。所述混凝土挤压墙板的制备方法包括以下步骤：混合硅酸盐水泥、硫铝酸盐水泥、石膏、骨料和水，搅拌，制备混凝土坯料；对所述混凝土坯料进行振动挤压，制备混凝土挤压墙板；所述振动挤压的工艺参数包括：震动的振动幅度为0.9mm‑1.1mm，主振频率为45Hz‑55Hz；铰刀的螺旋间距为65mm‑80mm，螺旋长度为290mm‑310mm，螺旋底径的锥度为35°‑45°，铰刀转速为210r/min‑230r/min；控制所述混凝土坯料行进速率的助力频率为35Hz‑39Hz。本发明制得的混凝土挤压墙板面密度小，密实度大，强度高，且干燥收缩值大、热胀冷缩系数小，安装后开裂率小。
