Use of Limestone Fines to Reduce Permeability of Concrete for Durability

Abstract: Traditional ly, the use of limestone fines (LF) in concrete is to replace either part of the cement or part of the fine aggregate, notwithstanding this, the authors are advocat ing that the LF should be better used as cement paste replacement, which is expected to improve the durability and sustainability of concrete at the same time.

What is the best replacement for cement in Concrete?

Concrete without cement is possible by the use of fly ash. The Green alternative to use of cement is fly ash which has same properties as that of cement both physically and chemically.

15 Factors Affecting Durability of Concrete

Quantity of cement used in concrete mix will also be a factor affecting durability of concrete. If cement content used is lower than the required, then water cement ratio becomes reduced and workability also reduced. Adding more water to this mix results in formation capillary voids which will make concrete as permeable material.

Use of Rice Husk Ash in Concrete: Literature Review

Bolla et al (2015) [India] carried out a research on the effect of partial replacement of cement with RHA on concrete. The cement has been replaced by rice husk ash accordingly in the range of 0%, 5%, 10%, 15%, and 20% by weight of cement for mix.

Mechanical properties and Durability Properties of Concrete

strength and flexural strength with 30% replacement are 33.69% and 13.09% more than conventional concrete 3. It was found that sludge based concrete when immersed in Acid solutions has better properties with 10% replacement of concrete. 2.2 Structural Performance of concrete by Partial Replacement of Cement with Paper Waste

Durability Performance of Bridge Concretes, Part II

ABSTRACT: A study was undertaken on the durability of high-strength concrete (HSC) produced using locally available materials in the State of Missouri. Thirty-six (36) different mixtures were produced as HSC. 30 % fly ash replacement by cement weight was

“Ground Granulated Blast Slag (GGBS) In Concrete – A Review”

GGBS concrete gains strength more steadily than equivalent concrete made with Portland cement. For the same 28 day strength, a GGBS concrete will have lower strength at early ages but its long term strength will be greater, the reduction in early strength will be most noticeable at high GGBS levels and low temperatures.

Durability and strength characteristics of high-strength

High VPP replacement rates with 20% cement mass decreased the properties of hardened concrete. 7. Adding PFs above 0.35% and 0.50% of concrete volume to V HSC F led to reduced compressive strength. However, indirect tensile and flexural strength improved with increased PF content. 8.

Low CO2 Concrete | U.S. Concrete

It could therefore be used in concrete, in combination with Portland cement, as part of blended cement. Concrete containing ground granulated slag develops strength over a longer period, leading to reduced permeability and more durability properties.

(PDF) Durability Studies on Concrete with Hypo Sludge as Partial Replacement of Cement

This paper summarizes the research work on the properties of hypo sludge when used as partial replacement for Ordinary Portland Cement (OPC) in concrete. OPC was replaced with hypo sludge by weight at 0%, 5%, 10%, 15%, 20% and 25%. 0% replacement

Durability of Concrete made with Marble Dust as partial

The test results show that the addition of marble dust as partial replacement of cement increases the durability of concrete against sulphate attack. By 10% replacement of cement with marble dust for both M25 & M30 grades produces more durable concrete when compared in terms of water absorption.

Development and freeze-thaw durability of high flyash-content

Abstract. Objectives were to investigate the effects on concrete strength, drying shrinkage, freeze-thaw durability, and air-void system parameters of replacing various amounts of portland cement with different types of fly ash and to compare selected characteristics of such fly-ash concretes and fly-ash concretes containing a high-range water-reducing admixture to those of a control mixture.

Heat resistant concrete

At higher temperatures (above about 800 degrees F), high-heat-resistant concrete is generally needed. Light-weight aggregates have proven to be more heat resistant and so that is the first step--use lightweight. When temperatures get extremely high, (above 1000 degrees F), calcium aluminate cement produces a fire-resistant concrete.

Cement Combinations for Durable Concrete
