TL;DR: Puertas et al. as mentioned in this paper investigated the feasibility of using and alkaline activated ground Turkish slag to produce a mortar without Portland cement (PC) by using three different activators: liquid sodium silicate (LSS), sodium hydroxide (SH) and sodium carbonate (SC) at different sodium concentrations.
467 citations
TL;DR: In this article, a comprehensive study on the durability properties of concrete containing polypropylene fiber and fly ash was performed, and the results showed that the positive interactions between polypropane fibers and fly-ash lead to the lowest drying shrinkage of fibrous concrete with fly ash.
319 citations
TL;DR: The results showed that ANN can be an alternative approach for the predicting the compressive strength of ground granulated blast furnace slag concrete using concrete ingredients as input parameters.
249 citations
TL;DR: In this article, high compressive and flexural tensile strength of alkali activated fly ash geopolymer mortars were presented, where NaOH was used as alkali medium that provides high pH value.
223 citations
TL;DR: The results showed that ANN and FL can be alternative approaches for the predicting of compressive strength of silica fume concrete.

TL;DR: The properties of concrete is universally compatible with any devices to read, and is available in the digital library an online access to it is set as public so you can download it instantly.
Abstract: Thank you for downloading properties of concrete. As you may know, people have look hundreds times for their chosen readings like this properties of concrete, but end up in malicious downloads. Rather than reading a good book with a cup of coffee in the afternoon, instead they juggled with some malicious virus inside their computer. properties of concrete is available in our digital library an online access to it is set as public so you can download it instantly. Our digital library hosts in multiple locations, allowing you to get the most less latency time to download any of our books like this one. Merely said, the properties of concrete is universally compatible with any devices to read.
1,701 citations
TL;DR: In this article, the authors provide a summary of knowledge and research developments concerning these ash-related issues, including alkali-induced slagging, silicate melt induced slagging (ash fusion), agglomeration, corrosion, and ash utilization.
691 citations
TL;DR: In this article, the effect of the addition of steel and polypropylene fibers on the mechanical and some durability properties of high-strength concrete (HSC) was investigated, and the results showed that the incorporation of 1% steel fiber significantly enhanced the splitting tensile strength and flexural strength of concrete.
521 citations
TL;DR: The morphology of concrete containing plastic materials is described in this paper to explain the influence of plastic aggregates and plastic fibers on the properties of concrete.
