Hybrid Modification of Stone Mastic Asphalt with Cellulose …

Basalt fiber is a mineral fiber manufactured by melting crushed basalt, a hard, dense and stable igneous rock, then physically forming fibers by spinning or extruding at about 1500 C. Basalt fiber has high elastic modulus and tensile strength and has no toxic reaction with air or water.

Sustainability of RCC Structures Using Basalt Composite Rebars

Basalt filaments are made by melting crushed volcanic basalt rock of a specific mineral mixture to about 1,400 to 1700 C for 6 hours. The molten rock is then extruded through special platinum bushings to produce continuous filaments of basalt fiber. There are

Application of crushed basalt increases pH on highly weathered tropical soils [], and helps mitigate soil acidification in agricultural regions more generally [] and production constraints in crops established on acidic soils (e.g. heavy metal toxicity in plants []).

Basalt Fiber Reinforcement

Basalt is heated only once. Further processing of BCF into materials is carried out using "cold technologies" with low energy costs. Basalt fiber is made from a single material, crushed basalt, from a carefully chosen quarry source. Basalt of high acidity (over 46

Rock dust helps soils store carbon and boosts crop yields, …

Adding crushed basalt to soils in the lab increases their potential to store four times more carbon dioxide, according to University of Sheffield study. Rock dust increases yields of cereal crops by up to 20 per cent and could reduce the need for fertilisers and agricultural lime. Simple method could help mitigate the climate crisis, improve food ...
