Abstract: The expediency of using scrap of normal weight cement concrete as a coarse aggregate in the composition of concrete is considered. The results of the study of water absorption of aggregate from normal weight cement concrete are presented. Samples obtained from scrap concrete of two grades M100 and M400 were used for the study. The obtained values were compared with a granite aggregate. Studies have shown that the water absorption of aggregate from scrap concrete is higher than from granite one, which must be taken into account when calculating the water-cement ratio of the concrete mixture. Research obtained make it possible to use scrap concrete as aggregates for various types of concrete. This significantly reduces the cost of purchasing raw materials, which in turn reduces the cost of manufactured products. The study of water absorption of aggregate from scrap concrete opens up new opportunities for industry and construction, contributes to the development and conservation of natural resources, economic growth and improvement of the environmental situation.
