AbstractAbout AuthorsReferences
At present, the off-shuttering method for reinforced concrete products forming is one of the progressive in the building material industry. It makes it possible to produce a wide range of products with high technical and operational characteristics as well as significantly expand possibilities of large-panel housing construction in the field of architectural-planning solu- tions. Hollow-core pre-stressed slabs are one of the most demanded products made according to the technique of off-shuttering forming. They are often used in housing construction. However, up to the present day, this type of products is insufficiently studied. There is no single regulation base in accordance to which the enterprises of building complex could pro- duce floor slabs. The article presents the results of control tests of reinforced concrete hollow-core floor slabs for strength and resistance to cracks, for which the composition of con- crete mixes has been selected. An expert assessment of parameters of slabs operation under the effect of concentrated loading is made
