Effect of several fillers on some basic mechanical properties of asphalt concrete

This paper presents the results of laboratory experiments to determine the influence of 4 different fillers (including conventional stone powder, Portland cement, rice husk ash, and fly ash) on some mechanical properties of asphalt concrete with Dmax of 12.5 (AC12.5).

Flexural performance of reinforced concrete beams made with locally sourced fly ash

The paper investigates the flexural performance of reinforced concrete beams in which fly ash from Vinh Tan power station was used to replace original Portland cement in the proportions of 0%, 10%, 20% and 40% by weight.

Influences of shrinkage reducing admixture on the mechanical properties, drying shrinkage, water absorption and porosity of portland cement mortar

Drying shrinkage is the main cause of early age cracking of concrete and mortar. A wide range of research has been conducted to reduce the drying shrinkage, including using fibres or chemical admixtures. This paper investigated the effect of shrinkage reducing admixture on the flexural strength, compressive strength, drying shrinkage, water absorption and porosity of mortar.

Effectiveness of ultra-fine ground slag in cement binders

This technique allows saving Portland cement without reducing significantly the concrete strength. The ability to obtain ultra-fine mineral fillers from industrial by-products with high specific surface area appears with grinding technology development.

Evaluation of interfacial bond strength between Portland cement concrete and asphalt concrete layers using bi-material SCB test specimen

Portland cement concrete (PCC) / asphalt concrete (AC) bonded components are seen in both conventional pavement structures as well as overlays. Due to the environmental and traffic loads, cracks occur at the interface of the PCC and AC layers and finally, may propagate through the interface or one of the layers.

CONCRETE. RAW MATERIALS

Concrete can be classified as composite material and that is a combination of different components which improve their performance properties. In general case binder component which can be in hard crystalline or amorphous state is considered as the matrix of composite material. In concrete matrix phase the grains of aggregates (dispersed phase) are uniformly distributed.
