The main type of products used for steel-teeming ladle lining is periclase-carbon. In order to improve corrosion resistance and resistance to thermomechanical loads, additional additives, such as spinel, and high alumina CMA cement, are introduced into the periclase-carbon products. In this paper, the effect of calcium aluminate-based additive on the properties of periclasecarbon refractories is investigated. It is assumed that there is a potential for the formation of magnesium aluminate spinel (MA) in periclase-carbon products with calcium-aluminate additives during heat treatment. Fused periclase was used as the raw material, the carbon component was represented by natural flake graphite in an amount of 10 wt% and a combined binder. An additive based on calcium aluminates was introduced, with a fractional size from 0 to 3 mm, while the amount of main fractions of fused periclase was reduced by the corresponding amount of the additive introduced. The compressive strength, apparent porosity, and bending strength values before and after coking firing were analyzed. The thermal coefficient of linear expansion, phase composition and microstructure of the products were also investigated.","PeriodicalId":19463,"journal":{"name":"NOVYE OGNEUPORY (NEW REFRACTORIES)","volume":"344 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139204579","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}

Such activity leads to a significant gain in strength, hardness and the production of high-strength concrete. It is shown that such an effect can be achieved by surface impregnation of concrete with sols (colloidal solutions) based on SiO2 nanoparticles. It is advisable to start impregnation from the third day of hardening under normal conditions. At this age, the main heat of the cement's own exothermic hardening reaction has already been released into the environment, and the introduction of additional energy will not cause a shift in equilibrium towards slowing down the hardening processes in accordance with the Le-Chatelier principle. The results of physico-chemical studies of concrete after hardening, explaining this effect, are presented.","PeriodicalId":19463,"journal":{"name":"NOVYE OGNEUPORY (NEW REFRACTORIES)","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139205118","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}
