Application of Household Waste as Aggregates for Concrete

Abstract

Abstract The use of recycled materials as a product of household waste recycling to reduce environmental pollution, as well as to obtain cheap aggregate for the manufacture of concrete is considered. During the laboratory tests, the strength of concrete was found by a non-destructive method of controlling the strength of materials - by the method of a shock pulse using an electronic strength meter IPS-MG4.01. The uniformity and class of concrete are determined on the basis of measuring the time and speed of propagation of ultrasound in them. Compression tests were carried out on parallelepiped samples of 390×190×188 mm in size, consisting of Portland cement, sand and household garbage. Significant differences were found from the indicators of the considered analogues, such as relatively low values of strength and frost resistance of the samples; but at the same time, the low cost of finished products due to the actually free aggregate, as well as the relatively low weight of the samples. Recommendations are given on the selection of the ratio of aggregate components to improve the properties of concrete as a whole. Areas of application for concrete blocks from household waste are offered.
