Structural Performance of Limestone as An Aggregate for

Due to its porous nature the coral / limestone coarse aggregate were pre-saturated roughly for a period of two hours to control absorption of the water in the concrete mix. To control slump, the limestone aggregates were pre-wetted before being used in the various mixes. This absorbed water is not part of the mix

Influence of bamboo fiber and limestone powder on the

limestone powder in self-compacting concrete significantly increases the workability of the mix due to the ability of limestone powder retain water in the fresh mix and also improve the stability and deformability of fresh SCC mix, thereby leading to improved strengths. This improvement can be attributed to the improve particle packing system, better water retention of the fresh mix, and

Engineering properties of lightweight aggregate

01/11/2016 Coarse and fine aggregate were mixed in a mixer for 2 min. Afterwards, cement, FA, and limestone powder were added and mixing continued for three minutes. A mixture of superplasticiser and mixing water was gradually added for 2 min while mixing continues. Mixing was continued for a

0.5%, 0.75%, it was observed that the coarse aggregate was evenly distributed across the spread, indicating good viscosity and stability of the mix. The presence of 10% percent limestone powder improved the workability of the concrete mix. This can be attributed to filler properties of limestone powder, which, affecting the cement particle

THE EFFECT OF ADDITION OF LIMESTONE

The use of limestone powder in concrete, particularly in SCC, has been widespread in Sweden and France, where limestone powder is stored in silos alongside the cement in ready-mix concrete plants. The addition of fine limestone powder can significantly improve the workability of self-compacting concrete [4] and it has shown to enhance the rate of cement hydration and strength development, as

total amount of limestone powder is almost not changing during 28 days hydration. The limestone powders fill in the interfacial transition zone between the matrix and aggregate, and make it become much denser, which is the reason why the porosity of concretes containing limestone powder is lower than that of traditional con-crete.

An overview on mixture design of

Nepomuceno et al. 47 developed a mix design methodology for SCC; binary and ternary blends of powder materials were used in combination of two cements and four additions that are limestone powder, fly ash, granite filler and silica fume. The mix design parameters were evaluated to achieve the required compressive strength and adequate fresh properties of concrete, mixes of two cements and
