Task 4 : testing Iowa Portland cement concrete mixtures ...

The drying shrinkage (εc) of a typical Iowa concrete (C-3WR-C20 mix) was tested at Concrete Technology Laboratory (CTL). The test results show that the ultimate shrinkage of the concrete is about 454 microstrain and the time for the concrete to reach 50% of ultimate shrinkage is at 32 days; both of these values are very close to the MEPDG default values. The comparison of the Iowa test data ...

Iowa State University Ames, IA 50011 November, 2010 . 1 ABSTRACT Portand cement pervious concrete (PCPC) has been increasingly used in concrete pavements during recent years. In addition to strength and permeability, abrasion durability is another important property of PCPC. In this paper, three potential abrasion test methods (Cantabro, loaded wheel, and surface abrasion tests) were ...

Influence of Cement Type on Stability of Concrete Mixture ...

The continuous tightening of emission limits for the production of harmful substances into the air and the rising price of emission allowances gradually force construction material producers to limit the use of binders with a high content of Portland clinker. In the production of concrete, this is achieved by using admixtures, which make it possible to reduce Portland cement doses.

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed. Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of ...

As such, in our research we test four possible measures to make concrete more bioreceptive: changing the aggregate to CEC (crushed expanded clay), adding bone ash to the mixture, increasing the wcf (water cement factor) and using a surface retarder on the concrete. Of these measures, changing the aggregate to CEC (p = 0.024), the addition of bone ash (p = 0.022) and the use of a surface ...

In 2012, after testing was completed for sulfate resistance on the Type IL cement, the Iowa DOT approved it for use in all concrete mixtures for any of their paving applications. Of note, this concrete mixture is a ternary blend, meaning it has three cementitious components. The PLC accounts for two of them (clinker with 10% limestone), and an additional 20% Class C fly ash. Compared to a ...
