How to Render Concrete Columns for a Smooth and Decorative Finish Using Sand and CementRendering sand and cement on decorative concrete columns is a crucial step in achieving a smooth, durable, and aesthetically pleasing finish for your structures. Start by preparing the concrete ...
Wet sand, straw and hay are still viable options for wet curing but burlap, cotton mats and synthetic covers are more efficient, less likely to cause staining or discolorations of the concrete and ...
Discover ways concrete petrographers evaluate how well (or not) curing operations are done in concrete construction. David Rothstein, Ph.D., P.G., FACI Mar 2, 2017 ...
But because the biochar makes concrete so much stronger, it may make it possible to shrink the amount of cement in the mix by 10%, which could offset the extra cost of making the biochar.
