An Analysis of Concrete Test Weight with Different Water Cement Factors Using Histogram in Quality Management
Siti Choiriyah, Jenny Caroline · IOP Conference Series Materials Science and Engineering · 2019
Concrete is a product with the composition of binding medium in which there is an aggregate pigments or particles. The binder is formed by cement and water mixture. Cater cement factor affects the compressive strength result. In producing concrete, a quality control is needed to obtain performance or process variation. In order to obtain the quality, statistical analysis using histogram method in the form tables and graphs is needed. From the measurement analysis results of 30 concrete test objects with different cement water factors getting uneven and unpredictable distribution results. The greater the cement water factor, the more dispersed the distribution of the cement will be but the weight of the concrete will decrease.
