    摘要: A glazed cement product and method for manufacturing thereof wherein the glazed cement product comprizes a foam light-weight aggregate, reinforcing steel under pretension or stress-absorbing layer around the reinforcing steel; an action of generating crack caused by a difference of coefficient of thermal expansion between the reinforcing steel and a portion of cement material while burning and cooling are carried out is absorbed by the foam light-weight aggregate, the stress-absorbing layer or pretension given to the reinforcing steel; a reaction of unreacted cement component is promoted by the hydration to harden for recovering mechanical strength.

    摘要: This invention relates to prestressed concrete units, to a method of manufacture of prestressed concrete units and to a mould system for use in such a method. The invention provides a method of manufacturing a prestressed concrete unit using a mould system comprising an elongate mould containing at least one prestressed element and an elongate hopper having an aperture, comprising the steps of locating at least one reinforcing element in a substantially perpendicular orientation to said mould; filling the elongate mould with concrete to form a first portion of the unit; locating the hopper over said reinforcing element in a substantially perpendicular orientation with the mould; and filling the hopper with concrete such that the concrete flows through the aperture to contact the concrete of the first portion.
