Making concrete mixes based on secondary aggregates, using the recycled aggregate

摘要

The purpose of the notification is the procedure for the use of recycled crumbs in concrete mixtures for the production of iron-bearing structural components. In order to make a concrete mixture on a recycled crumb, the design of a concrete mixture formulation shall be carried out in accordance with the following principles: for natural fractions, to include in the quantity of drinking water needed for the initial moisture of the recycled fraction,It is possible to use chemical additives to prolong the shelf life of the concrete mixture. Before making a concrete mixture, prepare a slightly thick 2 mm, in order to moisten slightly before its implementation into a concrete mixture, this is to introduce water into a brittle mixture, thus closing capillaries and pores in a brittle. This process will minimise fragile water status and limit the process of absorption of cement beginning. Do not use pre-soaked or wet impregnation in relation to the small frying stock Two millimeters. During the crushing of the concrete destruction part of the cement beginning is transferred to the cement shaft, which has the characteristics of a delayed bonding, which allows the bonding process to increase in the hardening process and the strength of the concrete.
