Technology in Practice (TIP)

This TIP explains the benefits of improved concrete quality

This TIP outlines the process of establishing strength of concrete mixtures as per ACI 318 and ACI 301

This TIP serves to improve the understanding of obtaining representative aggregate samples

This TIP helps understand reducing field samples to representative aggregate samples for testing

This TIP helps understand preparing the ends of cylindrical concrete test specimens prior to strength testing

This TIP outlines concepts on aggregate moisture for mixture proportioning and production of concrete

This TIP outlines the process of developing lab trial batch information for mixture submittals

This TIP outlines process for determining yield of concrete and evaluating problems with yield

This TIP outlines the determination of density of lightweight concrete for project requirements

This TIP outlines qualification tests and documentation for use of non-potable water as mixing water

This TIP facilitates the understanding of core testing for acceptance of concrete, the corresponding ASTM standard and how it is used. It does not supersede these standards.

This TIP facilitates the understanding of the change in slump that can occur during delivery of concrete.

This TIP addresses the limits on internal chlorides in concrete as addressed in the Building Code, ACI 318

This TIP facilitates the understanding of factors impacting the setting characteristics of concrete and the method to measure it (ASTM C403)

This TIP discusses the use of the maturity method for estimating in-place strength of concrete in accordance with one of the methods in ASTM C1074

This TIP provides guidance on evaluating strength test results used for acceptance of concrete to determine whether the testing procedures and test results indicate deficiencies in testing practices.

This TIP discusses the mechanisms of volume change and factors that impact shrinkage of concrete. It provides guidance on developing concrete mixtures for shrinkage specifications and the test method for shrinkage.

This TIP provides guidance to concrete producers on managing temperature of freshly mixed concrete to comply with specification limits or for quality reasons. In this TIP The term “initial concrete temperature” refers to the temperature of freshly mixed concrete.

This TIP provides guidance to concrete producers on managing returned concrete and options for disposal or reuse. It includes guidance on reusing freshly mixed returned concrete in accordance with ASTM C1798

This TIP discusses precision statements in test methods and how this information can be used in practice

This TIP outlines the process of proportioning and producing concrete mixtures for high strength and high modulus of elasticity.

This TIP discusses options for reducing the carbon footprint of concrete with equivalent performance while proportioning mixtures.

This TIP outlines the process of establishing required average values of any specified property for concrete mixtures to ensure compliance with acceptance criteria.

This TIP discusses the permeability property of concrete, when low permeability is required, test methods, and developing mixtures for low permeability.

This TIP discusses mechanisms of internal and external sulfate attack and methods and standards applicable to improve the sulfate resistance of concrete mixtures.

This TIP discusses a process, including tests of pastes, mortars, and concrete, to evaluate sources of cement and supplementary cementitious materials, as new materials become available for concrete production.
