Abstract. The use of self-compacting concrete mixes for producing paving slabs makes it possible to avoid the need for vibration compaction of raw material compositions. In this case, the resulting products have the required strength, resistance to abrasion and water absorption not exceeding the permissible values. For obtaining self-compacting concrete mixtures, ashes and slag, wastes generated by the industry and agriculture, can be used that will contribute to the solution of environmental problems, and also allow to improve the operational properties of the concrete product and increase the economic efficiency of their production. As a result of the conducted experimental studies, it was found that colored paving slabs based on self-compacting concrete mixes of the developed compositions meet the requirements of the standard TCVN 6476: 1999 (Vietnam). In addition, they have a wide variety of sizes and a wide range of colors which will contribute to the creation of a rational and aesthetically attractive urban landscape. The rough surface of such tiles makes them non-slip in rainy weather, it is important for the humid climatic conditions of Vietnam.
Key words: colored paving slab, self-compacting concrete mix, industrial waste, environmental pollution, fly ash, rice husk ash. - REFERENCES
