新材料及建筑工业的发展,必须依靠建工、建材密切配合,通力合作。这次会的一个特点,是建工、建材的同志在一起讨论有关的问题,这种做法非常好。找到了许多共同点:如发展墙体材料问题,发展水泥混凝土问题,砖的改造问题等。三十多年来的经验证明,新材料、新品种的发展,必须由建材和建工部门共同努力才能办到。水泥和混凝土,是建工、建材合作的重 The development of new materials and construction industry must rely on close cooperation between construction and building materials and full cooperation. One of the characteristics of the meeting was that the comrades of construction and building materials discussed the relevant issues together. This practice was very good. Many common points have been found: such as the development of wall materials, the development of cement concrete, and the reconstruction of bricks. The experience of more than 30 years has proved that the development of new materials and new varieties must be done by the joint efforts of the building materials and construction industry departments. Cement and concrete are important for cooperation in construction and building materials.
