The results of a DNA study conducted by the National Geographic 's "The Genographic Project", based on genetic testings of Filipino people by the National Geographic in 2008–2009, found that the Philippines is made up of around 53% Southeast Asia and Oceania, 36% East Asian, 5% European, 3% South Asian and 2% Native American genes.

Water–cement ratio. The water–cement ratio ( w/c ratio, or water-to-cement ratio, sometimes also called the Water-Cement Factor, f) is the ratio of the mass of water ( w) to the mass of cement ( c) used in a concrete mix: The typical values of this ratio f = w⁄c are generally comprised in the interval 0.40 and 0.60.
The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch. The test is popular due to the simplicity of apparatus used and simple procedure ...
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".

National home prices rose 6.3% from a year earlier, and 1.2% from the month before. But that price inflation is moving at a slower pace. “Last month’s all-time high came with all 20 markets ...
Abrams' law. Abrams' law (also called Abrams' water-cement ratio law) [1] is a concept in civil engineering. The law states the strength of a concrete mix is inversely related to the mass ratio of water to cement. [1] [2] As the water content increases, the strength of concrete decreases. Abrams’ law is a special case of a general rule ...
