Influence of Fine Aggregate Types on the . - ResearchGate

As the particle size distributions of different fine aggregate types are different from one another, a separate series with aggregate sizes manipulated to confirm to a single common particle size distribution was also carried out. The influence of fine aggregate type and proportion, on the hardened properties of concrete is.

Morphological characterization of concrete aggregates by . - SciELO

morphological characteristics of coarse aggregates from two different sources are determined using both, conventional methods and image analysis by means of Fourier descriptors. Mechanical properties of concrete prepared with coarse aggregates having different elongation indexes were evaluated. Results indicate.

ABSTRACT Title of Document: Crushed Returned Concrete . - DRUM

Three CCA aggregates at three strength levels were characterized. Thereafter, the coarse/fine aggregates and the three. CCA aggregates were used with various amounts to prepare concrete mixtures so as to investigate the effect on the fresh and harden concrete properties. The second objective of this research was.

The Effects of Different Fine Recycled Concrete Aggregates . - MDPI

May 18, 2015 . and (2) a method that produces only fine aggregate. Mortar specimens were tested using a variety of mix proportions to determine how the characteristics of fine recycled concrete aggregate affect the physical and mechanical properties of the resulting mortars. Our results demonstrate the superiority of.

Characterization and testing of rock aggregates of the Santa Marta .

Aggregates of intrusive rocks are the major source of crushed fine and coarse aggregates for use in concrete in several countries and they have to meet a number of specifications relating to strength and durability. This research reports the evaluation of aggregates of granitoids and associated rocks of Santa Marta Batholith,.

Characterization of Self-Consolidating Concrete for Design of .

. of coarse and fine aggregates, cement, water, and chemical and mineral admixtures. The required mixture constituents and proportions may affect the mechanical properties, bond characteristics, and long-term behavior, and SCC may not provide the same in-service performance as conventional concrete (CC). Different.

Durability and Shrinkage Characteristics of Self-Compacting .

Jul 16, 2015 . Natural fine aggregates (NFAs) and natural coarse aggregates (NCAs) were replaced by recycled fine aggregates (RFAs) and recycled coarse aggregates (RCAs), respectively, to produce 16 different SCC mixtures. NFA was crushed sand with a specific gravity of 2.42 and a fineness modulus of 2.38.

Self-Compacting Concrete – Procedure for Mix Design from .

The coarse aggregate content in concrete is generally fixed at 50 percent of the total solid volume, the fine aggregate content is fixed at 40 percent of the mortar volume and the water /powder .. Table 5 gives the recommended values for different tests given by different researchers for mix to be characterized as SCC mix.

Effect of size and type of fine aggregates on flowability of mortar .

The present study investigated how the aggregate characteristics namely individual size, grade and type affects flowability of mortar mixes. . In total, 103 mortar batches was made with three different sand to cement ratios [s/c] and two different water to cement ratios [w/c] to find out the flowability of mortar and tested using.
