Enhancing the efficiency of rebar use in reinforced concrete products’ manufacturing

Abstract

Abstract The article analyzes the state of rebar use in the conditions of construction enterprises of the Republic of Kazakhstan (RK). As a result of the research, it was found that today the domestic industry of construction materials is able to satisfy just a part of the needs of the Republic of Kazakhstan’s construction complex, and as a result, a significant share of the market is occupied by imported products, preventing a shortage of virtually all types of construction materials. The current situation has a negative impact on the prime cost of construction products’ manufacturing. It was also established that there is a high consumption of rebar for wastes, which exceeds the standards defined by State Standard and is about 2%. The consumption of rebar in this ratio also leads to an increase in the prime cost of reinforced concrete products’ manufacturing. For the effective use of reinforcing bars, which are the main components in reinforced concrete products’ manufacturing, it is proposed to separately use wastes of reinforcing bars, rods and wires to manufacture certain types of reinforced concrete products.
