The paper reviews the properties of cement composites reinforced with short fibres. The effect of natural fibres was investigated: cotton, sisal, jute, ramie, bamboo, and synthetic fibres: polymer and polypropylene. It was noticed that the fibres change
The natural Pozzolana is a siliceous material (SiO2) that reacts with the calcium hydroxide Ca(OH)2 produced during the hydration period of the cement; this inherent feature increases the cementitious property of the grout and improves the compressive strength of the concrete. However, the ...
Integrating artificial intelligence and green concrete in the construction industry is a challenge that can help to move towards sustainable construction. Therefore, this research aims to predict the compressive strength of green concrete that includes a ratio of cement kiln dust (CKD) and fly ash (...
Compressive strength of low cement/high fly ash concrete The effect of replacing 35 to 50 percent of cement by fly ash, on the compressive strength of lean concrete mixtures (350 lbs/yd 3; 210 kg/m 3) was investi... R Dan,PK Mehta - 《Cement & Concrete Research》 被引量: 51发表:...
Influence of Different Waste Materials on the Compressive Strength of Medium Strength Concrete1. INTRODUCTIONWorldwide various types of wastes are generated as a result of manufacturing and servicing industries irrespective of the nature of their products, discarding of these wastes is a big challenge ...
Effects of saturation degrees, freezing-thawing, and curing on geotechnical properties of lime and lime-cement concretes Lime-cement concreteSaturation degreeFreezing-thawingUnconfined compressive strengthThere are very limited researches carried out to investigate the influence of ...

The results show that partial cement replacement up to 20% produce, higher compressive strengths than control concretes, nevertheless the strength gain is less than 15%. In this paper we propose a model to evaluate the compressive strength of silica fume concrete at any time. The model is ...
The determination of the compressive strengths by the equation described here relies on determination of type of cement and age of concrete with the constant curing temperature.doi:10.2298/FUACE1103419JKsenija JankovićDragan NikolićDragan Bojović...
of rubber particle sizes on the compressive strength at the end of 3 d,7 d,28 d.Results showed that the compressive strengths decreased with increased amount of rubber aggregate replacement for mortar and concrete.By the same amount of fine aggregate replacement,the compressive strengths of 5 ...
As with cement, a full discussion on all of the types of concrete would bore most to tears, so we will stick with the basic product most people are familiar with. A residential sidewalk is likely to have a compressive strength of about 3,500 psi (pounds per square inch). That is the...
