Overview of Concrete Prefabricated Block and Pavement Development Abroad According to the Beijing Silicate Academy 1984 Academic Annual Conference Abstract Paper (First Volume), introduced by Beijing Institute of Municipal Engineering Shao Yilin, according to the first International Conference on Cement Concrete Brick Roads (September 1980, held at the University of Newcastle in the United Kingdom) Some papers and other relevant information prepared the paper “Overview of the development of foreign prefabricated cement concrete blocks.” This paper summarizes the development of large and small prefabricated cement concrete blocks commonly used as sidewalks and plazas in foreign countries. In terms of large blocks of bricks, in the British Standards B, S, and 368 in 1971, the size of the five squares and the three types of rectangles was specified. There are 30×30, 35×35, 40×40, 50×50, and 60× 60, 60 × 90, 60 × 75, 60 × 45 cm and other specifications, thickness 5 cm or 6.3 cm. error
