In Portland cement, 5% of its chemical composition is the gypsum mineral. The major compounds that make up Portland cement are tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite and gypsum. Once this process is complete, the cement is packaged and stored for use in concrete at a later date. Concrete can be created on site with the use of a rotating metal

Another large variation in chemical composition and digestibility is found among straw fractions. Research data from Xing Tingxian (1995) showed that stems from wheat straw have a much lower organic matter (OM) digestibility, compared with leaf blades and sheathes (Table 25). This low digestibility can be attributed to their high content of NDF and lignin. In rice straw, the OM digestibility
