摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 technology elements, u043fu0440u0438u043cu0435u043du00a0u0435u043cu044bu0445 in construction. purpose to improve the strength and uniformity of concrete. picking up the grain composition u0437u0430u043fu043eu043bu043du0438u0442u0435u043bu00a0 u0434u043bu00a0 concrete, taking into account the u0441u043eu043eu0442u043du043eu0448u0435u043du0438u00a0 diameter large and small aggregates.the number of aggregates depend on the equation, taking into account the true density, medium density u0437u0430u043fu043eu043bu043du0438u0442u0435u043bu00a0, large and small aggregates u0432u0438u0431u0440u043eu0443u043fu043bu043eu0442u043du0435u043du043du043eu043c with u043eu0441u0442u043eu00a0u043du0438u0438 fibers, aggregates cement grains and the test.
