Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...
As of 2017, there were more than 21 million E85 flex-fuel vehicles in the United States, [ 1] up from about 11 million flex-fuel cars and light trucks in operation as of early 2013. [ 20][ 21] The number of flex-fuel vehicles on U.S roads increased from 1.4 million in 2001, to 4.1 million in 2005, and rose to 7.3 million in 2008. [ 3][ 19] E85 ...
Self-consolidating concrete or self-compacting concrete (SCC) [1] is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).
Ready-mix concrete ( RMC) is concrete that is manufactured in a batch plant, according to each specific job requirement, then delivered to the job site "ready to use". [ 1] There are two types with the first being the barrel truck or in–transit mixers. This type of truck delivers concrete in a plastic state to the site. [ 2]
Consumer spending accounts for the vast majority of the US economy, about 70% of it. Spending accelerated sharply in the second quarter to an annual rate of 2.3%, up from 1.5% in the first quarter ...

The parts are in terms of weight – not volume. For example, 1-cubic-foot (0.028 m 3) of concrete would be made using 22 lb (10.0 kg) cement, 10 lb (4.5 kg) water, 41 lb (19 kg) dry sand, 70 lb (32 kg) dry stone (1/2" to 3/4" stone). This would make 1-cubic-foot (0.028 m 3) of concrete and would weigh about 143 lb (65 kg). The sand should be ...
