What are some ways to increase the strength of a concrete? - QuoraStrength of concrete can be increased by numerous methods: 1. Using cement of a higher grade. Higher the grade, higher is the surface area of the cement, and hence more surface of the cement particle is available for hydration. 2. Using mineral ad.increasing cement tensile strength,Compressive strength prediction of Portland cement concrete with .The rate of gain of strength is faster at start and the rate gets reduced with age [1]. In spite of considering the 28-day compressive strength for design purposes, actually concrete develops strength beyond 28 days as well. Most codes of practice do not consider the increase of strength beyond 28 days for design purposes.

Improving Concrete Properties with Fibers Addition - waset

properties with addition of cellulose, steel, carbon and PET fibers. Each fiber was added at four percentages to the fresh concrete, which was moist-cured for 28-days and then tested for compressive, flexural and tensile strengths. Changes in strength and increases in cost were analyzed. Results showed that addition of.

Do Fibers Increase the Tensile Strength of Cement-Based Matrixes?

ume of fibers in concrete, some evidence presented in this paper in- dicates that the fibers may substantially increase the tensile strength of matrixes. If this is true, then it is important to define conditions under which such beneficial interactions can occur. Keywords: composite materials; fiber reinforced concretes; fracture.

Strength of concrete can be increased by numerous methods: 1. Using cement of a higher grade. Higher the grade, higher is the surface area of the cement, and hence more surface of the cement particle is available for hydration. 2. Using mineral ad.

A study of factors affecting the flexural tensile strength of concrete .

The confining reinforcement increases ductility and large deflections in structures, providing a good warning of failure in the form of tensile cracks prior to complete failure of the flexure member. In the available literature, the relationship for predicting flexural tensile strength of low strength and high strength concrete has.

Strength Development of High-Strength Ductile Concrete .

Feb 23, 2014 . The maximum compressive strength achieved by using MK in concrete is 134 MPa [7]. The early strength gained is higher with the addition of MK in comparison with fly ash and silica fume [8]. Also increase in the tensile and bending strength of concrete and mortar with 10 to 15% MK is 32% and 38%,.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON .

in aggregate size, while the fracture energy of normal-strength concrete increases with an increase in aggregate size. High-strength concrete containing basalt and normal- strength concrete containing line yield higher fracture energies with higher coarse aggregate content than with lower coarse aggregate contents.

strength behavior of mortar strength behavior of mortar using slag as .

Ordinary Portland cement (OPC) mortar was also prepared as reference mortar. A total of 400 cube and briquet mortar specimens were cast and compressive as well as tensile strength of the mortar specimens were determined at curing age of 3, 7, 14, 28, 60, 90 and 180 days. Test results show that strength increases with.

Variables controlling tensile strength of stabilized sand with cement .

Variables controlling tensile strength of stabilized sand with cement and zeolite . In this paper, it has been shown that for the zeolite–cement–sand mixtures, qt increases via cement content (C) raise and porosity (η) reduction and a power function is well-adapted to fit both qt–C and qt–η. As a consequence, for each of the.

Factors Affecting the Mechanical Properties of Cement-Mixed Gravel

Nov 7, 2016 . Ordinary Portland cement with fly ash was employed as the cementation agent for preparing cemented samples. The results indicate that the unconfined compressive strength, the deformation modulus, and the tensile strength increase with the increase in the curing period. The ratio of tensile strength to.

Study on the strength characteristics of High strength concrete with .

Abstract. The study of High Strength Concrete (HSC) has become interesting as concrete structures grow taller and larger. The usage of HSC in structures has been increased worldwide and has begun to make an impact in India. Ordinary cementitious materials are weak under tensile loads and fiber reinforced.

Compressive Strength. 2015 Concrete Manual. 25. 3 dependent on strength, other properties to improve concrete durability are related to the strength. Concrete that fails to develop the strength expected of it is probably deficient in other respects as well. Note: For information purposes only, the plans and specifications give.

Quasi-static and dynamic experimental studies on the tensile .

Nov 10, 2017 . In this paper, based on splitting tests of Brazilian discs, the tensile strength and failure pattern of concrete and mortar were investigated under quasi-static and dynamic loadings with a strain rate of 1–200 s−1. It is shown that the quasi-static tensile strength of mortar is higher than that of concrete since.

Effect of types of fine aggregate on mechanical properties of cement .

strength. From the result table, it is observed that, a compressive strength of cement concrete increases after replacing a fine aggregate by artificial / crushed sand at 7 and 28 days. During the crushing process the manufactured sand have irregular shapes and more fine particles which are filling gap between coarse particle.

The Importance of Water/Cement Ratio « Concrete Countertop Institute

The simplest way to think about the w/c ratio is to think that the greater the amount of water in a concrete mix, the more dilute the cement paste will be. This not only affects the compressive strength, it also affects the tensile and flexural strengths, the porosity, the shrinkage and the color. The more the w/c ratio is increased.
