Functionality of mortar and concrete mixes is regulated by surfactants, which act as plasticizers. The molecular structure of these admixtures can be changed during hydration of alkali-activated cements (AAC). The objective was to determine the chemical nature of plasticizers effective for property modification of mortars and concretes based on AACs with changing content of granulated blast furnace slag from 0 to 100 %. The admixtures without ester links become more effective than polyesters when content of alkaline component increase. The admixtures effective in high alkaline medium were used in dry mixes for anchoring (consistency of mortar 150 mm by Vicat cone; 1 d tensile strength in bending / compressive strength of mortar 6.6 /30.6 MPа) and in ready-mixed concretes (consistency class changed from S1 to S3, S4 with consistency safety during 60 min; 3 d compressive strength of modified concrete was not less than the reference one without admixtures).","PeriodicalId":183715,"journal":{"name":"Collection of scientific works of the Ukrainian State University of Railway Transport","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131967683","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}

For passenger trains a аа is assumed equal to 0.7 m/s 2 . This criterion is a characteristic of the smooth running and the condition of riding comfort. You can increase the speed in curves in several ways: for example, by increasing the elevation of the outer rail, by raising the rate of unprecedented acceleration, etc. The first option requires lengthening the transition curves and re-laying the track, which is expensive and not always possible. In particular, it is difficult to do on lines with intensive cargo transportation. The second solution to the problem has much more opportunities to be realized. The article considers one of the options for increasing the speed of passing curves by increasing the permissible limit of the unrestricted acceleration to 0.9 m/s 2 . Experimental studies have established that the long-term and repeated impact of an unprecedented centrifugal acceleration up to 0.9 m/s 2 inclusive, most people tolerate satisfactorily, while the speed of passenger trains can be increased by 10-20 km/h depending on from the radius of the curvilinear section of the path. Consequently, the rate of passage of existing curves will change upwards with a minimum investment. In this case, a change in the magnitude of the outstanding acceleration in a large direction should not be accompanied by the deterioration of the passengers. If this condition is met, there is an adjustment of the scientific and technical documentation existing on the Belarusian Railways.","PeriodicalId":183715,"journal":{"name":"Collection of scientific works of the Ukrainian State University of Railway Transport","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122521043","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}
