When aggregate is quartered, what must be done?

When aggregate is quartered, it is imperative that it is well mixed to ensure uniformity and consistency in the sample. Quartering is a method used to reduce a bulk sample to a smaller size while avoiding bias in the material selection. By mixing the aggregate thoroughly after quartering, you ensure that any variations in size, shape, or material properties are evenly distributed throughout the sample. This practice is crucial for achieving accurate test results and for maintaining the integrity of the sample as it is prepared for further analysis or testing in concrete production. A well-mixed sample reflects the true characteristics of the larger quantity of material, making it suitable for the intended application in construction projects.
