Information for pairs0028: Concrete Compressive Strength --------------------------------- Abstract: Concrete is the most important material in civil engineering. The concrete compressive strength is a highly nonlinear function of age and ingredients. These ingredients include cement, blast furnace slag, fly ash, water, superplasticizer, coarse aggregate, and fine aggregate. --------------------------------- Sources: Original Owner and Donor Prof. I-Cheng Yeh Department of Information Management Chung-Hua University, Hsin Chu, Taiwan 30067, R.O.C. e-mail:icyeh@chu.edu.tw TEL:886-3-5186511 Date Donated: August 3, 2007 --------------------------------- Data Characteristics: The actual concrete compressive strength (MPa) for a given mixture under a specific age (days) was determined from laboratory.
