AbstractAbout AuthorsReferences
A possibility to use the waste of production of cement-woodchip boards (CWB) as components of cement mixes when producing new composite building materials is analyzed. To achieve the maximum utilization of these wastes, the optimal composition of components of mixes has been chosen. Physical-mechanical characteristics of cement composite materials with the use of CWB waste, density, central compression, bending strength depending on the type and quantity of additives (superplasicizer of polypropylene microfiber) have been experimentally studied. Dependences of compression strength and density depending on the amount of a superplasticizer introduced in the mix were constructed. It is revealed that the calculation of the amount of additive is to be made from the summary mass of a binder and CWB waste. It is proved that the introduction of additives into the wood-cement composition makes it possible to obtain an eco-friendly material not inferior in its physical-mechanical properties to the traditional concrete.
