While cement is a powdery substance that acts as a binding agent, ready mix concrete is a comprehensive mixture of cement, aggregates (like sand and gravel), water, and sometimes chemical admixtures to enhance specific properties such as setting time and strength.
Preparation Process
Cement must be mixed with water and aggregates at the job site to form concrete when prepared on-site. This process requires careful measurement and mixing to achieve the desired strength and durability. In contrast, ready mix concrete is prepared at a specialized facility, where experts batch the mix accurately to ensure consistency across all batches. This way, the contractor receives a product that’s ready to use upon delivery, significantly reducing on-site preparation time.
Quality Control
Another important distinction lies in quality control. Ready mix concrete typically undergoes controlled conditions in a batch plant, leading to a more uniform and high-quality product. Each batch is tested for compliance with various industry standards before it is loaded onto the mixing trucks. On-site mixing can introduce variability depending on the accuracy of measurements and the mixing process, potentially affecting the final strength and integrity of the concrete.
Cost Efficiency
The cost of using ready mix concrete can often be more efficient compared to preparing cement on-site. By eliminating the need for manual mixing of ingredients, ready mix concrete saves time and reduces labor costs. Additionally, as ready mix concrete is produced in larger quantities, it benefits from economies of scale, which can further lower costs for bulk users. The Home Depot
