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
Sugarcane bagasse ash has similar composition as cement so sugarcane bagasse ash can become replacement or partially replace cement. This mixture produces higher compressive strength than conventional concrete cement.Initiatives are emerging worldwide to strike a balance between the developments in ...
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 ...
This paper re-examines common notions and conventions regarding the compressive strength of concrete in general and of the uniaxial compressive strength of concrete in particular. A distinction is introduced between the strength of the specimen and the strength of the concrete as a material, and the...
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...
Kuwait has joined the world€s effort to encourage recycling by reducing the amounts of construction and demolition wastes sent to landfills, through the usage of recycled aggregates in Portland Cement concrete mixes. In this research, an experimental program was designed to test the effect of ...
Compressive strength is one of the most important properties of concrete in the hardened state. As well as compressive strength, other very important properties worth mentioning are compactness, workability, durability, cement class AFNOR NF EN 197–1 (2012), gravel/sandG/Sratio, granular rangeD/...
Modelling of the effect of the water-cement ratios on properties foam concrete Moreover, quantitatively simulation of the relationship between compressive strength at age 28 days and dry density of foam concrete is determined through experimental results for predicting the properties of foam concrete fro...
Generally, the BR algorithm gives a better overall performance, while underestimating the compressive strength compared to LM. Sensitivity analysis has also been investigated using linear and quadratic regressions. The findings showed that the highest contributors to concrete strength were cement and water...
