Chemical aspects of the application of basalt in cement
Basalt as coarse aggregate. Since basaltic rocks are not constant in their composition and their properties vary depending on the geographical location of a quarry, ABSTRACT: The purpose of this paper is to investigate the feasibility of using basalt aggregates in concrete mixes. Concrete is the most important engineering Experimental Study on the Use of Basalt Aggregate in

Physical Properties and Microstructure of Concrete with Waste Basalt
The gradual substitution of sand with basalt dust leads to the sealing of aggregate composition, which results in lower air content in the concrete mix and thus a 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 Chemical aspects of the application of basalt in cement

Mechanical Properties and Microstructure of Basalt Fiber
Basalt fiber (Fig. 1): produced by a company in Guangdong (see Table 2 for basic performance and size of basalt fiber). Coarse aggregate: continuous graded granite gravel, particle size 5–20 mm. Fine aggregate: native river sand, particle size 0–4.75 mm. Water: laboratory tap water. Water reducing agent: naphthalene series efficient waterThree different aggregate types, Rilem sand, basalt sand, and recycled waste concrete, were used separately as the main component in the mixtures. The chemical properties of BS and RWC are given in Table 2. The Rilem sand with a specific gravity of 2.64 is a standard sand variety produced in accordance with EN 196–1 [41]. The main Effect of basalt fiber on metakaolin-based geopolymer

(PDF) Experimental Study on the Use of Basalt
The reference concrete mix was modified by replacing sand with granite and basalt aggregate in the same fractions. Five series of concrete mixes made with CEM I 52.5R cement were testedThe gradual substitution of sand with basalt dust leads to the sealing of aggregate composition, which results in lower air content in the concrete mix and thus a lower porosity of hardened concrete. Along with the increased basalt dust content in the sand mass, the increase in concrete mixture density is observed.Physical Properties and Microstructure of Concrete with Waste Basalt

Chemical aspects of the application of basalt in cement
Consequently, the interactions of basalt in powdered or aggregate form and basalt reinforcement with the cement matrix are specified from a chemical point of view. Finally, suggestions for future research inspired by the revealed gaps in the current knowledge are formulated. Durability properties of concretes made with sand and Figure 5 shows that the natural, granite and limestone sands had low MBV, less than 0.63 g/kg, whereas the basalt and gritstone sands had MBV above 1.73 g/kg. This suggests the presence of clays in the basalt and gritstone sands which may result in an increased water and admixture demand when used in a concrete mix .

Physical Properties and Microstructure of Concrete with Waste Basalt
The natural aggregates are one of the main components in the production of concrete. Although deposits of natural aggregates lie on the earth’s surface or at low depths and belong to common deposits, the shortage of aggregate, especially natural sand, is presently observed in many countries. In such a situation, one is looking for other This research elucidates the idea of eco-friendly concrete and highlights the benefits attainable from its effective practice towards sustainable construction materials. The design mix employed a water/cement ratio of 0.5, a concrete mix ratio of 1:2:4, varying percentages of 2.5 mm seashells, 4.75 mm river sand as fine aggregates, and granite 20 Effective Economic Combination of Waste Seashell and River Sand

Basalt fibre-reinforced concrete: review of fresh and
Furthermore, basalt fibre has a length of 24 mm and a length of 50 mm reinforced concrete with content of 1–3%, and its tensile strength is considerably increased by 1.80 times. While most fibre lengths have high tensile strength, when using fibre lengths of 24 mm and 50 mm there is no significant difference.Malaysia produced 118 million tons of aggregates in 2011 and 160 million tons in 2015 (Survey 2018). Figure 2 shows a similar increasing trend in the USA, where aggregate production increased from 1.34 billion tons in 2015 to 1.53 billion tons in 2019. About 72% of the aggregates were used as construction aggregates, particularly road A systematic review of the utilization of waste materials as aggregate

Microstructure analysis of hydraulic concrete using crushed basalt
This paper presents an experimental study of the microstructure of concrete using crushed sands and river sand. Three sands with different geological nature have been investigated in this work. Sand from crushed basalt (SB), sand from crushed gneiss (SG) and sand from river Sanaga (SS) were used for the formulation of these While current global aggregate consumption of 32–50 billion tonnes per year 19, 20 is dominated by high (per capita) production in North America and China (Figure 1 A), the greatest relative increase in production is projected to occur in LMICs. 21 Here, large resource and extractive industries contribute significantly to developing economies.
