Mechanical properties of self-compacting high-performance concrete
This paper presents the results of experimental work on the mechanical properties of self-compacting high-performance concrete (SCHPC) containing fly ash (FA) and silica fume (SF). The paper focused on the feasibility of substituting the ordinary Portland cement with waste supplementary cementing materials to decrease the In addition to cement, sand, gravel, and water, the current investigation of the influence of additives on the compressive strength of concrete at 28 days includes fly ash, silica fume, and slag. 315 concrete compositions with various amounts of additives are trained and tested using an artificial neural network. Concrete strength is largely affected Investigation of the effect of mineral additives on concrete

Properties of concrete modified with mineral additives
Mineral additives (zeolites, SiO 2 micro dust etc.) are some of the most prospective components of concrete in the development of new building materials such as high performance concretes, special concretes absorbing heavy metals or suppressing radioactive radiation. These additives modify and accelerate Portland cement hydration The test results show that the addition of superplasticizer and fine mineral additives enabled the UHPC to be produced at an extremely low water/binder ratio of 0.14–0.18, Ultra high performance concrete is characterized primarily with high strength, and when it is reinforced with steel fibers or steel tubes, exhibits high ductilityPreparation of Ultra-High Performance Concrete with

Effect of aggregate and fibre types on ultra-high-performance concrete
Ultra-high-performance concrete (UHPC) is one of the most modern and advanced concrete technologies, having compressive and flexural strengths of more than 150 and 17 MPa, respectively [37,38]. UHPC possesses a high-density microstructure due to the use of high content of cement, ultrafine mineral additives, fine quartz sand in In this study, investigation effect of the replacement of zeolite powder with a cement in high-performance concrete. Experimental study conducted to determine a mechanical property. To predict the experimental findings, statistical techniques are used to compare all the obtained experimental results with artificial neural networking (ANN). The Artificial neural networking prediction of the mechanical

Effect of superabsorbent polymer characteristics on rheology
Changes of rheological properties in ultra-high performance concrete (UHPC) suspending mortar incorporated superabsorbent polymer (SAP) were investigated. The effect of chemical composition of two SAP types (S1, acrylamide/acrylic sodium copolymer and S2, acrylamide polymer) and the S1 SAP with mean particle sizes of 95.1 The influence of four naturally occurring mineral additives (zeolite, diatomite, trass and bentonite) on the hydration and properties of cement pastes and mortars was investigated. The materials change the phase composition, heat of hydration (determined by calorimetry) and mechanical properties of composites.
