Description

The invention relates to building materials, namely compositions of wood concrete mixtures.

The purpose of the invention is to accelerate hardening, increase the strength of arbolite after heat and moisture treatment and reduce its hygroscopicity under operating conditions, as well as simplify the technology of preparing the arbolit mixture by eliminating CaCI from the composition, zastohatel.

For the preparation of arbolita, three mixtures of ingredients are prepared, kg / m:

While maintaining the strength of arbolite unchanged, the use of the proposed composition allows either to reduce the consumption of a substance for making arbolite products, or at a constant consumption in the Order. Circulation 640 Subscription Branch of PPP Patent, Uzhgorod, ul, Proektna, D

Before mixing, the crushed wood is pre-soaked

in water. The mixing of aline cement, wood and water for each of the compositions is carried out manually for 1 minute, after which the residual water is added

and the mixture is stirred for another 2 minutes

Then, the mass is placed in cm-sized molds and compacted on a laboratory vibrating plate at A 0.4 mm and f 3000 Hz. Wherein

Next, the samples were incubated for 2 h, then placed in a laboratory steam chamber and

steamed in a mode of 2-6-2 hours at an isothermal holding temperature of 40 ° C. After drying the samples at 50 ° C, their properties are determined,

reduce the duration of heat treatment, increase formwork turnover and reduce the cost of thermal energy. In addition, the manufacturing process of arbolite products is simplified.
