Development of a New Method of Aggregate Treatment in the Technology of Lightweight Concrete–Wood Concrete

Abstract

The article deals with the results of the research and development of a new method of the aggregate preparation in the technology of lightweight concrete–wood concrete. It is developed as a new method for gentrification of organic aggregate—rice husk in the electrochemically activated cathode water with addition of a quicklime of 1%-1.5% by weight of water and adjusting the pH of the liquid medium to 14-16. It is specified that the addition of quicklime in the treatment of the alkaline water and soaking the organic aggregate in it greatly intensifies a strength gain of wood concrete. Technical novelty of the method is confirmed by the RK preliminary patent no. 16644. The results of the conducted experiments led to the enhancement of wood concrete strength made by the proposed method of organic aggregate up to 2.45 MPa in the rice husk, 2.6 MPa in the wood flake, 2.35 MPa at guza units, 2.2 for sliced rice straw, and 2 MPa for broken rice reeds.
