February 26, – acu Any applicable errata are included with individual documents at the time of purchase. Errata are not included for collections or sets of documents such as the ACI Collection.

According to ACI R, when determining the duration of curing, consideration should be given to the concrete properties that are desired in addition to compressive strength development. Concrete Cracking October 30, – Curing August 27, – 4: Compressive strength development is the primary reason curing of concrete is required, and SCP products help achieve even better performance that moist-cured concrete, long held as the gold standard of curing concrete.

This document provides requirements for alternative methods for curing concrete. Figure 2 shows the performance of concrete treated with SCP products versus air and moist cured concrete.

ACI 308.1.pdf

At least two ASTM C09 axi are currently working on standards to better evaluate the performance of colloidal silica. The objective of curing is to allow the concrete to meet performance parameters; SCP products produce those performance parameters at a rate equal to or better than moist curing.

Figure 3 below shows the performance of treated concrete tested for drying shrinkage, another important reason curing is required, demonstrating improvements over moist-cured control samples. An important consideration when acu products for use with concrete is that ASTM develops standards to generate performance numbers while ACI writes the guides and specifications that are used to put the 380.1 generated into practice.

The appropriate duration of curing will depend on the property that is the slowest to develop.

Figure 4 shows the performance of treated concrete in water permeability testing in a ack pressure environment, another reason curing is often called out.

Because SCP products penetrate into the concrete, they do not form a surface membrane. In other words, the semi-evaporable and non-evaporable water continues to be made available for hydration until it is consumed or an equilibrium state is achieved when SCP products are used.

The full and complete returned product will be accepted if returned within 308.11 days of receipt and in salable condition. For a listing of and access to all product errata, visit the Errata page. This specification has default settings that may or may not be applicable to a specific project.

Figure 1 above shows the percentage of strength gain 3008.1 with various curing methods. These alternative methods are not necessarily equal in effectiveness, cost, effect on project schedule, or impact on other aspects of the project. These items are not eligible for return. July 30, – 2: Concrete — 3081 vs.

This specification addresses curing methods applied after placement of concrete and does not apply to internal curing use of saturated lightweight aggregate or other materials to provide supplemental water or to accelerated curing heat curing.

Guide for Specifying Underground Shotcrete. The reaction products formed fill capillaries and shut down liquid water transmission. While membranes degrade over time, and water ponding methods cannot 038.1 continued indefinitely, the use of SCP products provides a continuous curing environment. Additionally, SCP products become a permanent part of the concrete while membranes and water ponding are temporary.

ACI Specifications for Curing Concrete by ACI Committee

This action makes SCP products an effective waterproofing agent, even under hydrostatic pressure. ASTM C membrane-forming curing compounds were developed as a solution to the need for acj time-saving alternative to 30.81 ponding. The materials, processes, quality control measures, and inspections described in this document should be tested, monitored, or performed as applicable only by individuals holding the appropriate ACI certifications or equivalent.

Until those standards are available, and ACI The action works in the other direction as well, holding in water that would normally evaporate at early ages.

Compressive Strength as a Function of Age for a Variety of Curing Conditions ACI R According to ACI R, when determining the duration of curing, consideration should be given to the concrete properties that are adi in addition to compressive strength development.
