Chloride Ion Diffusion Resistance of Bulk Hydrophobic Concrete: Comparison of w/c and Dosages
Post-cast application of hydrophobic agents onto hardened concrete is successful at reducing external ion diffusion into cement paste, this work examines pre-cast application of hydrophobic admixtures in fresh concrete.

The Lengths of Admixture Tracts [PDF]
Abstract The distribution of admixture tract lengths has received considerable attention, in part because it can be used to infer the timing of past gene flow events between populations. It is commonly assumed that these lengths can be modeled as independently and identically distributed (iid) exponential random variables.

Plastic Shrinkage Cracking in Concrete
Plastic shrinkage cracking in concrete is mainly a physical process, in which chemical reactions between cement and water do not play a decisive role. It is commonly believed that rapid and excessive moisture loss, due to evaporation is the primary cause

NATURAL AND CHEMICAL ADMIXTURES IN CONCRETE- A REVIEW
To understand the effect of different natural and chemical admixtures on the properties of conventional and high strength concrete, an extensive literature review was done. It is known that chemical admixtures are composed of substances that are added to

Influence of Admixture on Phenotypes
AbstractIndividuals of European descent have historically been the focus of genetic studies and possess relatively homogenous genomes. As a result, analytical methods have been developed and optimized with such genomes in mind. African‐descent and Latino individuals generally possess genomes of greater architectural complexity due to mosaic genomic ...

Throughout human history, large-scale migrations have facilitated the formation of populations with ancestry from multiple previously separated populations. This process leads to subsequent shuffling of genetic ancestry through recombination, producing variation in ancestry between populations, among individuals in a population, and along the genome ...
