sampleAnswers": ["A typical concrete mix consists of cement, water, coarse and fine aggregates. The correct ratio is crucial; too much water reduces strength while too little affects workability. Coarse aggregates provide bulk and strength, while fine aggregates fill gaps and improve texture.", "The key ingredients in concrete are cement, water, aggregates, and sometimes admixtures. The cement binds the ingredients, while the water activates the cement. A balanced mix is essential because excess water can weaken the final product, and properly sized aggregates support structural integrity."
