The coarse NA was crushed limestone with sieve size ranges between 5 and 22.5 mm. The grading of the NA is shown in Table 1. The RCA was attained by crushing old concrete specimens that …
Basalt was used to create the AC 13 mixture, and the coarse aggregate was replaced by limestone and BOF slags by coarse-fine composition method, respectively. Volumetric and mechanical properties were studied to evaluate the influence of geometric characteristics of BOF slag coarse aggregate on asphalt concrete.
This study aims to produce the HSSCC series by using basalt and waste marble aggregates in certain volumetric ratios instead of limestone-based crushed …
The production of aggregate for the infrastructural development of the country has been increasing for the last three decades due to the high urbanization rates in the main cities of the country and the ever-growing demand for basic infrastructural facilities. The environmental impact of both fine and coarse aggregate production is …
consists of 50% coarse aggregate and 50% fine aggregate in weight. The selected aggregate gradation was in accordance with the General Directory of Turkish Highway (GDTH) recommended gradation for granular base layers. ... Freeze–thaw is one of the major problems in the region where the basalt aggregates are used. As seen in Fig.3, …
The coarse aggregates include mixtures of basalt with natural basalt aggregate (BA), raw recycled aggregate (RRA), and improved recycled aggregate (PRA), respectively. ... However, the main aggregate used in this experiment is basalt, and the air content partially increases because a large number of pores (large and small) are included in the ...
Basalt. Coarse Aggregate. Compressive Strength ABSTRACT. This present research was on the comparison of the efficacious use of basalt and granite as coarse aggregates in concrete work. In order to obtain the basis for comparison, physical and structural tests were conducted on the different materials of the concrete and the …
Instead of limestone-based coarse aggregates, waste marble and basalt aggregates were used at 25, 50, 75, and 100 % ratios by volume. Thus, a series of eight different HSSCCs and a control HSSCC ...
An experimental program is set up to test the effect of basalt aggregate content and its combinations with lime stone with variation of percentages in concrete mixes. Different aggregate ...
Basalt in cementitious composites can be utilized in various forms. In its natural state, depending on its grain size, it can play a role of a pozzolanic active component or coarse aggregate. Basalt can also be used as concrete reinforcing material of different shapes and sizes, such as fibers, ropes, fabrics, or rods/bars.
Coarse aggregates (CA) Two types of CA, granite and basalt are used to prepare the PQC mix in the present study. Granitic aggregates are derived from intrusive igneous rocks and are composed predominantly of silica. The grain or texture varies from fine to coarse. Granitic aggregates are more abrasion resistant and hard to break.
According to the current study, clam seashells have been partially replaced for coarse aggregate. There is still a lack of exploration concerning its strength properties of concrete, when sea shell used as a replacement for coarse aggregate. Basalt Fiber has tangible malleable property; thus, it can be utilized as a fibre reinforcement material.
In order to fulfill the objective, several different size basalt coarse aggregates were used in research, and a regression model of VCA was established. As long as the established regression model is valid and reliable, then it can be used to reveal the forming mechanism of VCA of the specific coarse aggregates and a universal law …
Coarse aggregate is a term used in construction to describe a type of material that is commonly used in the production of concrete. It is typically made up of various materials such as gravel, crushed stone, and recycled concrete. The size of the coarse aggregate can vary, but it is typically between 3/8 inch and 1.5 inches in diameter.
