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%),(,0%) respectively.
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.

Abstract This paper presents the results of a study that investigated the improvement of the mechanical properties of recycled concrete aggregate (RCA) produced by adding chopped basalt fibers (BF) with contents of 0.1%, 0.3%, 0.5%, 1%, and 1.5% by total volume of the mix to treated and untreated recycled aggregates. The recycled aggregates were surface treated by pre-soaking them in a 0.1 M ...
This study evaluates the static and fatigue bond behavior in basalt fiber-reinforced polymer (BFRP) bars embedded in concrete. For bond behavior under a mono-tensile load, BFRP bars with four types of surface patterns (round, rectangular, cross-winding, and spiral-winding) were adopted, and 20 groups of rib parameters were introduced for round-type BFRP bars.
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 matrix-aggregate 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
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.
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 ...
Feb 15, 2020· To understand the durability of basalt fiber-reinforced polymer (BFRP) bars for the reinforcement of concrete structures applied in marine environments, BFRP bars with 20-mm concrete covers were immersed in ocean water or simulated seawater at room temperature (~23 °C), and the evolution of the thermomechanical properties was studied.
Study of Sawdust Concrete Properties as Construction Materials Mayur Patel #, Kush Patel #, Akshay Patel#, RonakPrajapati, Utsav Koshti # Department of Civil Engineering, Institute of Technology, Nirma University Abstract— Construction industry relies heavily on conventional materials such as cement, basalt and sand for the production of ...
The most famous model known in prediction of dynamic modulus for asphalt concretes is the Witczak and Hirsh models. These models didn't use the mineralogical and chemical properties of aggregates. Witczak models used the passing or refusal percentage to sieve diameters and Hirsh model used the volumetric analysis. All models developed until now considered that the aggregates were ...
Recycled concrete aggregate (RCA) has been produced in Qatar since 2009 as a result of the extensive construction and demolition activities. The purpose of this study is to study the effect of using RCA combined with a newly developed basalt macro fibers (BMF) on the flexural behavior and ultimate capacity of beams with different replacement ...

For all the concrete mixes, two sizes of the coarse aggregates, ranging from 20 to 10 mm and smaller than 10 mm, were used. River sand with fineness modulus of 3.55 was used as fine aggregate. 1, 2, and 3% of chopped Basalt fibers (measured with respect to the total volume of the concrete) were used as microreinforcement.
concrete aggregate. Basalt is an important rock used in the construction of bridges, pavements of highways, railways and other engineering works. It is not used for very important buildings because of its dark colour and the quality of not taking good polish. ... study. aggregate. concrete. ...
