Abstract
Concrete is an important building material used in the construction of different types of civil engineering structures. The production of cement, an integral part of concrete releases large amounts of carbon dioxide, green house gases that exacerbates climate change. In order to reduce the environmental impact of cement production, supplementary materials can be used. The addition of supplementary cementitious materials to concrete improves the overall properties of concrete through pozzolanic activity. This study is designed to evaluate the feasibility of using Ground granulated blast furnace slagand Silica fume as substitute for cement in concrete. It can be reduced the cost of concrete and the rate of cement consumption. In our research, we investigate the strength properties of concrete using certain percentage of GGBFS and Silica fume with the replacement of cement. The cement was replaced by 20%, 30% and 35% GGBFS and 5%, 10% and 15% Silica fume respectively. The w/c ratio, fine aggregates and coarse aggregates were kept as per the design mixes. M40 grade concrete is used in the experiment. The specimens were prepared. The concrete was tested for fresh properties such as workability and mechanical properties like compressive strength for 7 days, 14 days and 28 days respectively. The test results conclude that the combined addition of GGBFS and silica fume as substitute of cement at various amounts gives positive effect on workability and strength.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
