Grout is a dense fluid which is used to fill gaps or used as reinforcement in existing structures. Grout is generally a mixture of water, cement, and sand and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of pre-cast concrete, filling voids, and sealing joints such as those between tiles.Common uses for grout in the household include filling in tiles …
Concrete for Pumping| Concrete Construction Magazine
Small concrete pump is specially designed for the small construction projects. So with the features of small size and flexible movement, it can adapt to various construction sites easily.It doesn’t have large capacity, but the it still can pump the concrete with perfect performance and high quality.
Additional samples may be field cured (non-standard) for the purpose of early ‘stripping’ strengths, that is, form removal, evaluation of curing, etc. but the standard cured cylinders comprise acceptance criteria. Concrete tests can measure the "plastic" (unhydrated) properties of concrete …

For well-rounded aggregates this maximum size can be increased to 40 percent. Hence, a one and one-half inch gravel aggregate could be used in a pumping system with four inch openings. The properties of fine aggregate (sand) are more important in the design of pumpable concrete mixes than the properties of coarse aggregate.Author: Author/Concrete-Construction-Staff
