This black sand is made of crushed basalt rock with granulation 0.5 - 2 mm. It is used in the production of high-strength and ultra high-strength concrete. Since it contains no fines, it is particularly suitable for concrete based on our FLOWSTONE® and TEGNO® special cements. Our recipe suggestion for ultra-high performance concrete (UHPC): 27.5 kg basalt sand 0.5 to 2 mm + 25 kg TEGNO® + 325 g superplasticizer FLUP®-PCE-375 + 4.25 kg of water.
