Study on the Fluidity and Strength Properties of High Performance .

Study on high performance concrete using crushed sand is hardly found in Korea. In this study it was investigated that the effect of the crushed sand on fluidity and compressive strength properties of high performance concrete. Blending crushed sand (FM: 3.98) produced in Namyangju, Kyunggido and sea sand (FM: 2.80).

Strength and Durability Evaluation of Recycled Aggregate Concrete .

This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON .

The effects of aggregate type, size, and content on the behavior of normal and high-strength concrete, and the relationships between compressive strength, flexural strength, and fracture energy are discussed. The concrete mixtures incorporate either basalt or crushed line, aggregate sizes of 12 mm ('h in.) or 19 mm.

Hydration mechanism and strength properties of recycled aggregate .

Jan 30, 2017 . Strength properties of recycled aggregate concrete were enhanced with addition of ceramic powder and ceramic coarse fraction, more than the strength .. is focused on ascertaining the influence of ceramic content, fine and coarse fraction, on the strength properties of concrete made with crushed concrete.

The Study of Relationships between Aggregates Properties and .

Crushed aggregates were selected with different petrographic, but similar grading curves. The main objective of this research is to investigate the effect of aggregate on the mechanical properties of fresh and hardened concrete, as well as identified the relationship between aggregates properties and concrete strength.
