The use of dispersed mineral fillers makes it possible to realize the potential of binders to a large extent, which leads to an increase in the physico-mechanical, operation-al and technical properties of composite binders, as well as building materials based on them, and reduces the con-sumption of expensive binders. The creation of highly effective composite binders is based on the management of their production technology at all stages: the selection of raw materials, the development of optimal compositions, the use of mechanical activation of raw materials, the modification of composite binders with functional chemical additives, and some other methods. The use of volcanic ash in the world is quite diverse, it is used not only as addi-tives for building materials, but also it has found its application in medicine. Many countries are beginning to use volcanic ash as a building material. The article presents the results of obtaining binder compositions of optimal composition based on Portland cement and volcanic ash. Experimental studies of the granulometric composition have been carried out, the results of tests of binder compositions of the compositions: cement – volcanic ash, pre-pared in a vibratory mill, have been presented. The results of physical and mechanical tests of binder compositions with different content of volcanic ash, activated for 10 and 20 minutes in a vibratory mill, have been obtained. Re-search work has been carried out to study the microstructure of volcanic ash.","PeriodicalId":127090,"journal":{"name":"Construction Materials and Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133351584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Air heat pumps are more promising than geothermal ones, but their use in cold climates is limited by formation of frost on the evaporator heat exchanger. This paper presents a heat pump unit with a system for breaking ice with using oscillatory circuits. The air heat pump unit with MOVEBIT anti-icing system, including the oscillatory circuit, has been developed. It was tested in the temperature range from -26 up to +10 . The transformer ratio is determined as the ratio of the heat received to the operation expended. The calculation of heat output was carried out using a computer program that includes the flow main parameters. The calculated and experimental values of the coefficients are compared. Studies have shown that a change in the temperature of the air entering the evaporator of the pumping unit with the anti-icing system does not significantly affect the energy efficiency of the equipment under test. The MOVEBIT outdoor air heat pump allows to obtain a conversion factor in the range of 46 when operating in areas with outdoor temperatures down to -27 and can compete with geothermal heat pumps. Measurements of the sound impact of the anti-icing system showed the need to reduce it by 30 %.","PeriodicalId":127090,"journal":{"name":"Construction Materials and Products","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122713468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
