FIELD: chemistry. ^ SUBSTANCE: invention relates to construction industry and chemistry, and more specifically to making light concrete products with organic filler, which is mainly wooden. The method of making light concrete products with organic filler, which is mainly wooden, involves mixing crushed organic filler with cement, electrolyte and water, moulding the product, electro-stabilisation with direct current in pulses with alternating polarity with stoppage of not less than 2 minutes before each polarity change for a period of not less than 45 minutes, holding the product until structural strength gain. Organic filler is first mixed for 1.5-2.5 minutes with water and electrolyte solution. Cement is then added and the mixture is stirred for 1.5-2.5 minutes. Electro-stabilisation is done in a concrete form, working surfaces of which are electrodes, at temperature of the mixture not above 35C, with current density of 1 A/m2 per 1 cm of the thickness of the product in pulses with alternating polarity with duration of 3 minutes. After structural strength gain of the product and finishing work, outer surfaces of the product are hydrophobised. ^ EFFECT: increased efficiency of the technology of making light concrete products with organic filler, cutting of duration of erecting buildings with simultaneous increase in stability of their operating characteristics in different weather conditions. ^ 1 cl |
