Discolored Concrete: 3 Causes and What You Can Do

2 天前  Add too much water, and the concrete project will be very porous and sensitive to breaking. Add too little, and it will be hard to work with, and the improper mixing might also make it unstable. Therefore, a darker color might actually signify that your concrete is more on the solid side, as long as the mix properly absorbed all the materials.
