1. Concrete strength is most directly controlled by which parameter? A. Aggregate size B. Cement color C. Water–cement ratio D. Aggregate shape C. Water–cement ratio [ANSWER] Rationale: The water–cement (w/c) ratio determines the porosity of the hardened paste: more water yields more capillary pores and lower strength. While aggregate properties and cement type influence strength, their effect is secondary to the w/c ratio. Cement color and aggregate shape have only indirect or mi...
