The Influence of Ceramic Ball as a Fine Aggregate in Concrete
Abstract. River sand, a non-renewable resource, is used in concrete as a fine aggregate, which is called filler material that fills the voids in concrete. This paper provides outcomes of compressive strength of concrete by using the ceramic ball as substitutes of fine aggregate that is compared with nominal mix concrete.

What Causes Cement Balls? - Concrete Construction
Cement has a high affinity for water. So upon contact with water, the dry cement powder acts like a sponge and globs up. The balls form as these globs roll against the inside drum surface. The key to prevention is to program a material-loading sequence that deposits the cement and the coarse aggregate into the drum at the same time.
Can I Make Concrete with Just Sand and Cement? (What To Do)
Image by jarmoluk via Pixabay. Just as you can make no-fines concrete without sand, you can create a concrete mix that incorporates a high proportion of sand. However, concrete that incorporates higher levels of sand compared to coarser aggregates will be weaker overall and cannot be used for structural applications or where support or load-bearing abilities …
