An actual scientific problem in current concrete science is poor knowledge of the modifying with plant waste. At same time, waste benefits from other types because it a recycled raw material. A promising technological approach to introduction components based on processing coffee production into concrete. This study aims investigate use biochar additives spent grounds (biochar grounds—BSCG) technology cement composites and identify rational formulations. biochar-modifying additive was produced by heat treatment these wastes additional mechanical grinding after pyrolysis. The phase composition manufactured BSCG determined, which characterized presence phases such as quartz, cristobalite, amorphous carbon. results showed that increases water demand for pastes reduces cone slump mixtures. Rational dosages have been determined improve properties As result tests, ideal situation ratio be at maximum 8% not exceed this rate. For pastes, most effective content 3% (3%–4%). compressive flexural strengths were 6.06% 6.32%, respectively. Concrete’s strength increased 5.85%, absorption decreased 6.58%. obtained prove feasibility using composite reduce consumption solve environmental recycling
