Outlook for the use in concrete of aggregates with high

Outlook for the use in concrete of aggregates with high

Outlook for the use in concrete of aggregates with high sulfate content. European standard limits the sulfate content in aggregates in order to avoid any concrete degradation due to internal sulfate attack. As a result some materials natural aggregates concrete demolition waste excavation materials cannot be used in concrete production.

Longterm sulfate attack on recycled aggregate concrete

Longterm sulfate attack on recycled aggregate concrete

ABSTRACT. The effect of recycled concrete aggregate RCA on concrete performance against external sulfate attack ESA is not yet fully known. In this paper recycled aggregate concretes RAC with 0 50 75 and 100 of RCA contents were evaluated after 10 years of exposure immersed in 50gl sodium sulfate solution.

SULFATE RESISTANCE OF ROLLER COMPACTED CONCRETE

SULFATE RESISTANCE OF ROLLER COMPACTED CONCRETE

The resistance to sulfate attack improves with increases in cement or coarse aggregate content as concrete becomes more dense and impermeable. Length change of RCC samples increases with increasing immersion age and stabilizes within 3-4 months after the initial contact. No mass of concrete residues is found for any specimens tested in this study.

Sulfate attack in concrete

Sulfate attack in concrete

Sulfate attack in concrete and mortar. Sulfate attack can be external or internal. External due to penetration of sulfates in solution in groundwater for example into the concrete from outside. Internal due to a soluble source being incorporated into the concrete at the time of mixing gypsum in the aggregate for example. External sulfate attack .

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

HOW FINE AGGREGATES AFEECTS CONCRETE MIX DESIGN

Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus moisture content specific gravity and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.
