Keywords: Basalt fiber, compressive strength, split tensile strength, Flexural strength I. Introduction Concrete is the most used construction material around the world. It uses cement, fine aggregate and coarse aggregate as its constituents. Because of its extensive use the consumption of cement is increasing now days.
Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber.

In order to investigate the influence of basalt fibers (BFs) on the mechanical performance of recycled aggregate concrete (RAC), some groups of RAC specimens were first tested involving different ...
The reference samples were also made, based on the same ingredients. Only aggregate was a mixture of gravel and basalt – aggregates commonly used for the high strength concretes production. In addition, the interfacial transition zone between cement paste and aggregate was analyzed (using SEM).
Hence, the life cycle assessment (LCA) of the production of recycled coarse aggregate (RCA) is conducted and compared with that of natural coarse aggregate (NCA) in accordance to the Indian scenario. In this context, the primary data during the production process of RCA and NCA are collected from the respective processing facilities.
Aggregate Preparation Two types of aggregate (basalt and limestone) are used in this study for asphalt mixture production to investigate the zycotherm nanomaterial effect on their behaviour and to compare them with respect to their usage with this material. The aggregates were brought from two different sources in Turkey and their ...
molten lava after solidification. The production of basalt fiber consists of melt preparation, extrusion, fiber formation, application of lubricates and finally winding. method is also known as spinning. A fiber is a material made into a long filament with density generally in the order of 300g/cm2 of 50cm. The aspect ratio of
composite and to reduce labor and energy costs in its production. For achieving high performance of modern concretes, high demands on materials for their preparation are placed. Of particular importance is selfcompacting concrete reinforcement with basalt fiber that has high chemical resistance in alkaline environment of concrete.
Aggregates in Concrete Concrete Technology 10 Rocks are classified according to origin into three major groups: 1. Natural Mineral Aggregates Sand, gravel, and crushed rock derived from natural sources. (a) Igneous Rocks formed on cooling of the magma (molten rock matter). Granite, basalt: hard, tough, strong Excellent aggregates

Aggregates, both fine and coarse, take about 6575% by volume of concrete and are important ingredients in concrete production. The parent materials of aggregates are derived mainly from volcanic activity. The dominant rock for coarse aggregate production in Ethiopia is generally basalt while ignimbrite is most commonly

Desert sand is treated to be used as an aggregate for concrete, a method for producing an aggregate for concrete is provided, and to an aggregate for concrete is provided. The aggregate is obtained by crushing desert sand in a highpressure roller press, wherein, in a first stage, the desert sand in a bed is crushed by pressure exposure, and then forms agglomerates.
