The method of mixing will also be specified, as well as conditions that it may be used in.This allows a user of the concrete to be confident that the structure will perform properly.
Many factors need to be taken into account, from the cost of the various additives and aggregates, to the trade offs between the "slump" for easy mixing and placement and ultimate performance.
A mix is then designed using cement (Portland or other cementitious material), coarse and fine aggregates, water and chemical admixtures.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
SCC looks very different from conventional concrete while mixing.
From concrete air meters and rebound hammers to rebar locators and tests for corrosion, you'll find the concrete testing equipment you are searching for, here on the Humboldt website.
It can be also categorized as high performance concrete as the ingredients are the same, but in this type of concrete workability is increased.
Increased fines contents can be achieved by increasing the content of cementititious materials or by incorporating mineral fines.
Admixtures that affect the viscosity of the mixture are especially helpful when the grading of available aggregate sources cannot be optimized for cohesive mixtures or with large source variations.
Humboldt provides a complete selection of concrete testing equipment for fresh and in-place concrete structures in accordance with ASTM, AASHTO and other standards.
