A higher ratio gives a too fluid concrete mix resulting in a too porous hardened concrete of poor quality. Often, the concept also refers to the ratio of water to cementitious materials, w/cm. Cementitious materials include cement and supplementary cementitious materials such as ground granulated blast-furnace slag (GGBFS), fly ash (FA), silica ...
A hummingbird feeder with red nectar. Hummingbird feeders, rather than dispensing seed, supply liquid nourishment to hummingbirds in the form of a sugar solution. The solution is normally 4 parts water to 1 part white sugar. Only pure refined white cane or beet sugar should be used, according to experts: [3] [4] [5] [6]

Their addition allows to decrease the water-to-cement ratio of concrete or mortar without negatively affecting the workability of the mixture. It enables the production of self-consolidating concrete and high-performance concrete. The water–cement ratio is the main factor determining the concrete strength and its durability. Superplasticizers ...

W. R. (Robert) Sullivan was the inventor of an early hummingbird feeder as well as an advocate for banding hummingbirds and hummingbirds living in zoos.. In 1932, Sullivan invented a hummingbird feeder designed to prevent other birds or insects from drinking from it, which he produced and sold locally around Kerrville, Texas.
Separate paste mixing has shown that the mixing of cement and water into a paste before combining these materials with aggregates can increase the compressive strength of the resulting concrete. [69] The paste is generally mixed in a high-speed , shear-type mixer at a w/c (water to cement ratio) of 0.30 to 0.45 by mass.
