菱苦土是一种优良的胶结材料,但以往用于建筑工程中的制品,只有门窗、地板、天花板、窗台板、楼梯扶手等非承重构件,而不能用它来制造屋架、梁、桁条、过梁等承重或次承重构件。这主要是由于菱苦土的抗拉强度较低,而它的制品又是用苦卤(MgCl_2)烧制的,对铁件有腐蚀作用,不能与钢筋很好的配合使用。因而限制了菱苦土在建筑工程中的广泛使用。山东省昌潍建筑工程局木材加工厂在技术革命运动中,受到省科学研究所研究芦苇混凝土的启发,经大胆创造,利用芦苇配筋,试制成功了芦苇菱苦土桁条。这种桁条经多次试验,结果证明性能良
Ramon is an excellent cementitious material, but in the past, the products used in construction projects were only non-load-bearing components such as doors, windows, floors, ceilings, sill plates, and stair railings. They cannot be used to make trusses, beams, and beams. , Liang Liang, such as bearing or sub-loading members. This is mainly due to the lower tensile strength of magnesite, and its products are fired with bittern (MgCl 2 ), which has a corrosive effect on iron pieces and cannot be used in conjunction with steel bars. Thus limiting the extensive use of magnesite in construction projects. In the technological revolutionary movement of the Changyi Construction Engineering Bureau of Shandong Province, the wood processing plant was inspired by the research of the reed-concrete in the Provincial Institute of Science. After boldly creating and using reeds and reinforcing bars, the reed rhizomatous rammed-tar soil strip was successfully produced. This purlin has been tested many times and the result proves that the performance is good
