compressive strength. There are many variables that influence recycled concrete compressive strength (grading curves, maximum size fraction, natural aggregate source, cement class, possible admixtures, etc.) which have not been taken into account. In fact, it is really difficult to take all these variables into account.
The fine aggregate was manufactured sand consisting mainly of calcium carbonate and natural river sand composed mostly of quarts. The gradation of the two types of fine aggregate was shown in Figure 1, and the physical characteristic was shown in Table 1. The mix proportion and workability of cement-based mortars are listed in Table 2.

Jan 01, 2021· The aim of this work was to evaluate the relationship between the basic properties of different fine aggregates, such as specific gravity, fineness modulus and bulking, and then relate them to the compressive strength, water absorption and sorptivity. This would facilitate the engineer in choosing the fine aggregate based on its basic properties.
proposed relation predicts the compressive strength of RCA concrete that closely matches the experimental results. Index Terms — Compressive strength, concrete, recycled coarse aggregate, regression analysis. I. INTRODUCTION Due to rapid urban development along with trade and

TESTING AND RESULTS Compressive Strength The strength in compression has definite relationship with all other properties of concrete. ... (KN) Compressive Strength for 28 Days(MPa ...
Jan 06, 2020· The relation between the flexure strength and compressive strength depends on the type of coarse aggregate used, except in high strength concrete, because the properties of aggregate, especially its shape and surface texture, affect the ultimate strength in compression very much less than the strength in tension or cracking load in compression ...

Jun 10, 2019· The curve in Fig. 4 describes the relationship between the equivalent aggregate size (average aggregate size of the narrow gradation aggregate ) and compressive strength. It can be seen that when the aggregate size is below a certain value (about 7 mm), the compressive strength increases rapidly with the increase of aggregate size.
Mar 20, 2018· The test result by Somna proved that the ground fly ash could be remarkably useful to facilitate the compressive strength and durability of recycled aggregate concrete with the same water to binder ratio. 2.1.2. Fine Aggregate and Coarse Aggregate. Locally produced river sand was used as fine aggregate in this experimental program.

Therefore, this research work is conducted to study the relationship between the cube compressive strength and cylindrical compressive strength of concrete made with recyclable old concrete as coarse aggregate. As mentioned earlier the use of old concrete in new concrete is not new. Several scholars around the globe have conducted

compressive strength of concrete. Ruiz (1966) found that the compressive strength of concrete increases with an increase in coarse aggregate content until a critical volume is reached, while Bayasi and Zhou (1993) found little correlation between compressive strength and coarse aggregate content.
Nov 01, 2002· This reveals the influence of the fine aggregate source on the interface sand–paste in concrete because coarse aggregate was the same for all mixtures. Download : Download full-size image; Fig. 8. Relationship between compressive strength of concrete and mortar.
qualitatively related to its compressive strength. In this work the effect of ultra fine slag (Alccofine) replacement on the mechanical properties of high strength concrete is studied. It has been found that use of ultra fine slag not only improves the compressive strength of buconcretet also improves the workability and fluidity of the mix.
Jan 25, 2021· At this circumstance, this study mainly investigates the rheological behavior and compressive strength of concrete containing recycled fine aggregate (RFA) with particles in different size ranges.

2. The Properties of Fine Aggregate: The properties of fine aggregate also influence the ratio of tensile to compressive strength of concrete. 3. The grading of aggregate also has been found to influence this ratio. 4. Effect of Moisture: The moisture condition of concrete influences the relation between the flexural and compressive strength.
Both coarse and fine recycled aggregates decrease the compressive strength. Typical results for the relationship between compressive strength and curing time are presented in Figure 2. The results concern mixes with RFA. All the tested mixes present a decrease in strength. This is mainly due to the added water for the work ability correction.
