Fiber polymer has been extensively used to improve the mechanical properties and durability of concrete. However, the studies of the effect of fiber polymer on the dynamic performance of recycled aggregate concrete (RAC) is still very limited. In this study, we prepared two types of RAC formulations: RAC reinforced with basalt fibers (BFs) and RAC reinforced with polypropylene fibers (PPs ...
Blending a certain proportion of basalt fiber into concrete improves the toughness of concrete, which prevents cracking and avoids the brittle behaviors. In this paper, the compressive, tensile, and flexural tests of concrete with different basalt fiber contents were carried out. Then the test phenomena, failure modes, and mechanical properties were compared and analyzed to derive the ...
Mar 20, 2020· This study investigates the effect of basalt fiber (BF) on the mechanical properties, chloride content carried in coral aggregates, and water absorption of CAC. The results indicate that with the increase in fiber content, the mechanical properties and water absorption resistance of basalt fiber reinforced coral aggregate concrete present an ...
In this research study, mechanical properties of silica fume bagasse ash plain concrete (SFBAPC) and silica fume bagasse ash basalt fiberreinforced concrete (SFBABFRC) are studied. A total of fifteen concrete mixes are prepared for three separate concrete groups (five for each concrete group).

In this paper, three typical concrete aggregates, namely limestone, granite and basalt, were chosen for the study. To investigate the interface interaction of aggregatecement paste, the change of ion in cement solution was tested. Furthermore, the pattern and composition of .
Aug 27, 2014· Currently, reuse of solid waste from disused infrastructures is an important environmental issue to study. In this research, polymer concrete was developed by mixing orthophthalic unsaturated polyester resin, artificial microfillers (calcium carbonate), and waste aggregates (basalt and limestone) coming from the recycling process of concrete sleepers.
Most recently Kishore et al. have presented a study for exploring the feasibility of basalt aggregates in concrete mixtures. Using normal laboratory test and slump test analysis, the authors have...
Essentially, primary aggregates can refer to any granular material formed from a natural rock substance, in this instance basalt. Whitemountain produces aggregates suitable for use in ready mixed concrete, precast concrete, highway construction, drainage and asphalt.
Feb 22, 2016· [4,5]. The use of steel slag in concrete would enhance the strength of concrete, especially tensile strength [6]. On the other hand steel slag was used in the field of highway construction. Resistance to low temperature cark and roughness were improving by using steel slag aggregate as compare to basalt aggregate.
The splitting tensile strength of concrete is improved by 15% when basalt fibers with 2% volume fraction are added to the concrete mix. A significant increase of up to 75% is noticed in the flexural tensile strength of basalt FRC, with better post‐peak residual strength compared with the plain concrete.
strength concrete containing basalt is controlled by the strength of the rock and the interfacial strength at the matrixaggregate interface. The flexural strength of normal strength concrete containing the basalt or limestone used in this study is not affected by aggregate type, and is limited by the matrix strength and the strength of the ...

compacting recycled aggregate concrete reinforced with basalt fibre. The study comprises development of SCC mix design of M25 grade and Basalt Fibers are added to the SCC later mixes and their fresh, hardened and durability properties are determined and compared with conventional mix. The study presents considerable improvements in pulse velocity
Key Words: Basalt Fibre, Geopolymer Concrete, flexural strength, fly ash,ggbs 1. INTRODUCTION Concrete is the most used construction material around the world. It silicon and the aluminum in the fly ash are activated by a uses cement, fine aggregate and coarse aggregate as its constituents. Because of its extensive use
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 percentage combinations were used in this study for basalt and limestone (0%,),(25%,75%),(50%,50%),(75%,25%),(100 %,0%) respectively.
This study evaluates the static and fatigue bond behavior in basalt fiberreinforced polymer (BFRP) bars embedded in concrete. For bond behavior under a monotensile load, BFRP bars with four types of surface patterns (round, rectangular, crosswinding, and spiralwinding) were adopted, and 20 groups of rib parameters were introduced for roundtype BFRP bars.

The purpose of this research is to investigate the feasibility of using basalt aggregates in concrete mixes. The researcher has designed an elaborate experimental program that included a variation of basalt percentages in concrete mixes. The laboratory investigation included measurements of compressive strength, indirect tensile strength, flexural strength, thermal conductivity, permeability ...

Some studies dealing with basalt has been concluded that basaltic aggregates increase the quality of concrete (Tasong et al., 1998; Özturan and Çeçen, 1997). The physical properties of basalts vary greatly because of the range of textures and compositions. Flowing temperature of basalt ranges from 1,000 to 1,220 °C.
