It was observed that the crushing value of RCA-25 and RCA-40 coarse aggregates are 35.9% and 30.4%, respectively, which are significantly higher than Basalt coarse aggregate (21.2% crushing value). The higher the aggregate crushing value will lower the strength of coarse aggregate.

0% basalt (as a control blend), 25% basalt, half basalt, 75% basalt and basalt for every arrangement of outline blend. The arrangement of every blend was 60% coarse total of 20 mm size and 40%coarse total of 10mm size. Fine total limits to zone-I. Key words: basalt aggregates, compressive strength, concrete, etc 1.

As seen in this table, the flakiness index of the basalt aggregate is 25%. In general, strong and hard or brittle rocks produce a higher proportion of flakes than weak rocks, although …

Compressive strength for basalt 36.39N/mm2 while 37.16N/mm2 for granite. 24.81N/mm2 tensile strength for basalt while 12.57N/mm2 for granite, 31.83N/mm2 flexural strength for basalt while 27.97N/mm2 for granite. From the above results, it can be deduced that basalt has higher strength properties than granite.

2.1 Materials. The raw materials used in all mixtures include Portland cement (strength grade of 42.5), silica fume, and quartz sand (0.1–2 mm). Commercial basalt and calcined bauxite aggregate with two grades (60% of 3–5 mm aggregate and 40% of 5–8 mm aggregate) were used (see Fig. 1) to produce UHPC.The tested relative densities …

Several test methods investigate the properties of the aggregates. Some of these tests, for example, the aggregate impact test (Palassi and Danesh, 2015, Engidasew and Barbieri 2014), the slake durability test (Topal and Doyuran 1997; Miščević and Vlastelica 2011) or the Nordic test (Erichsen et al. 2011; Krutilová and Přikryl 2017), are …

The basalt aggregate has been used by many researchers since ancient times, especially in the production of the related building materials, because of its high strength, hardness, and easy accessibility. ... it is demonstrated that there is a strong dependance of energy consumption on the compressive strength of concrete. Energy of …

As basalt aggregate is a natural aggregate also available in plenty at low cost, an economical and relatively high strength concrete is obtained by using basalt aggregate as coarse aggregate in concrete mixes. Coarse aggregate replacement with 25% basalt to increase in Compressive Strength, Split Tensile Strength . For M50 Grade with basalt …

Types of Aggregates. Common aggregate materials include sand, gravel, basalt, granite, pebbles, and feldspar.. Aggregates are classified by size into: Coarse Aggregates: Typically gravel or crushed stone, with particle sizes greater than 4.75 mm. They bear the main load in concrete and significantly impact its strength and …
