Abstract
This article presents the issues related to using by-products and waste materials in constructionand mining industry. The current applications of selected materials in various areas are presented, with particularfocus on cases in the construction and mining industries, where waste-based composites sealed with various hydraulic binders are used to build new structural elements or just as fills and backfills. In the next part of the revivew, the methodology and selected results of shrinkage tests on concrete composite samples with the addition of various amounts of additives and price tests to reference samples without dispersed reinforcement are presented and discussed. Research has been carried out on the subject of balance between concrete and the semi-finished product used.

This article presents the issues related to using by-products and waste materials in constructionand mining industry
Reuse of spoil material and by-products Semm to be extremly attractive idea for mining industry that produces a lot of waste and needs large amounts of backfill material for safe mining production [10,11,12]
Apart from the widespread use of pieces of rubber from car tires as filling in artificial surfaces of football fields or in communication construction [6,7], research is conducted on the possibility of using construction waste in geotechnics and miningwith particular emphasis on the lack of negative environmental impact [9,10,11,15]
Summary
The growing demand for infrastructure and the increasing prices of building materials cause interest in new technological solutions as well as create opportunities for reusing previously produced building materials [1,2,3,4,5]. Ubysz and Łuszczyk are conducting research on the possibility of using steel fibers from recycled tires as reinforcement for concrete as well as the use of other materials as reinforcing fibers [6,7]. In the step researchers undertake the replacement of the seemingly indispensable component of concrete, which is aggregate, with waste composite rods [5]. Another example of attempts to replace cement binder is making mixtures based on industrial wastes dissolved in water [15]. In addition to the use of recycled materials as semi-finished products for concrete mix, research is conducted on the possibility of using it in the other areas. The article presents selected results of tests carried out on concrete samples with the addition of waste basalt fibers used as dispersed reinforcement
