Durability Properties of High Performance Foamed

The foamed concrete was prepared using the high-efficiency foaming agent. When water to cement ratio (w/c) is 0.42-0.46, the dry density and compressive strength are 400-500 kgm-3 and 1.25-1.5Abstract. Ultra-high performance fibre reinforced concrete (UHPFRC) is an innovative cement-based engineering material. The mechanical properties of UHPFRC not only depend on the properties of the concrete matrix and fibres, but also depend on the interaction between these two components.Materials Special Issue : High Performance Concrete MDPI

Compressive behavior of fiber reinforced high-performance concrete

In the research area, mainly plain concretes were analysed and only a few works dealt with the subject of high-performance concretes with the addition of polypropylene fibres, among others [17,[35Fire events remain a severe hazard despite significant progress in the construction industry. The high-temperature resistance of concrete structures highly depends on the properties of their ingredients. The present study provides an analytical review of the available experimental studies investigating the influence of high Buildings Free Full-Text The Effects of Supplementary MDPI

Study on the Performance of Foam Concrete Prepared from

Although the energy structure has been gradually enriched in recent years, China, as the world’s largest producer and consumer of coal, still accounts for more than 50% of resources. Therefore, in this paper, the high carbon fly ash raw ash (HCFARA) was mechanically activated, and the flotation was treated to obtain decarburized fly ash concrete with very high durability and very low permeability is consid-ered to have high-performance properties. Bickley and Fung (2001) demonstrated that 40 MPa (6,000 psi) high-performance concrete for bridges could be eco-Fig. 17-1.

Compressive behavior of ultra-high performance concrete confined with

This paper presents an experimental study on the compressive behavior of ultra-high performance concrete (UHPC) confined with fiber-reinforced polymer (FRP) composites. A total of 18 cylindrical specimens were prepared from UHPC containing 2.5% of micro steel fibers by volume, among which 6 were unconfined and 12 were confined High-performance concrete (HPC) is obtained by inclusion of mineral admixtures like silica fumes and fly ash to the normal concrete. Consumption of natural materials such as sand, natural aggregates, and limestone produces environmental degradation. Similarly, industrial by-products such as fly ash, silica fume, and ferro slag Predicting Strength Properties of High-Performance Concrete

Application of Mineral Admixture in High Performance Concrete

b) Main technical approach of preparing high performance concrete . 1) Using high-quality mineral admixtures with large amount is the technical core of preparing high performance concrete. Because high performance concrete requires high compactness, and it is difficult to meet such requirements with a single cement as binding material.The quick rise of intelligent technologies promotes the development of the construction industry into a new phase. As an advanced cement-based materials, ultra-high performance concrete (UHPC) breaks the performance upper limit of traditional concrete materials, which has also been empowered by intelligent techniques.Intelligent design and manufacturing of ultra-high performance concrete
