2016/09/22· The compressive strength decrease is evident for the highest substitution of natural aggregates; at 20% substitution, the compressive strength decrease of GA concrete was about 50% with respect to RC. This could
Aslani et al. (2018) explored the fresh properties, compressive strength, splitting strength and compressive stress-strain behaviour of concrete using waste recycled concrete aggregates and rubber granules.
Finally, 15 cm cubes and 100 × 100 × 30 cm concrete slabs were cast to estimate the compressive strength of concrete using Schmidt rebound hammer, core, and cube testing. 2.3. Sample preparation The compressive strength
The compressive strength of recycled aggregate concrete is relatively lower up to 15% than natural aggregate concrete. The variation also depends on the original concrete from which the aggregates have been obtained. The
concrete, but the crushed clay brick aggregates concrete showed better performance as the age of concrete increases and average reduction in compressive strength were 33.5% at the age of 7 days but it becomes only 20% at the age of 56 days compared to natural aggregates concrete.
Effect of aggregate type on Compressive strength of concrete Abdullahi. M International Journal of Civil and Structural Engineering Volume 2 Issue 3 2012 793 SG CA = Specific gravity of coarse aggregate Table 1: Mix composition of concrete (1m3)
13.3. Strength and durability of concrete using RAs Previous research (Richardson et al., 2009) suggests that the use of RA in concrete produce a reduction in compressive strength when compared with aggregates.
2019/06/04· Using crushed waste concrete and clay brick as alternative aggregates has particular significance since they can considerably reduce the problem of waste storage as well as help in the preservation of NA [1,2]. Therefore, recycled
The unconfined compressive strength, q u, of the original concrete increased with an increase in the cement/water ratio in weight, c/w (). Several months after production, the original concrete masses were crushed manually by
Cubes of concrete were prepared and tested to study the compressive strength. The result indicate that the concrete having brick bats as aggregates may be termed as medium light weight concrete having a density between kg/m3.
2018/08/02· The compressive strength result on concrete revealed that CT10 (i.e 10% crushed tile replacement) produced the highest compressive strength (27.5, 29.054, and 32.15N/mm 2 ) for 7, 14, and 28days. Also CT10
Crushed Limestone Concrete Aggregate Concrete, along with steel and wood products' are the basic building materials of our modern society. Concrete is made by mixing sand, course aggregate, water and cement.

American Journal of Engineering Research (AJER) 2018 w w w . a j e r . o r g Page 339 The effect crushed glass on compressive strength of coarse glass-aggregate concrete is shown in Figure 2. From Figure 2, results show that
2015/05/14· Compressive strength of concrete produced with the recycled aggregate was in the range of 41 to 52 MPa. Mix 4 had the lowest compressive strength. This was expected due to the nature of grade 4, which has poor particle
