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.

Compressive Strength as a Function of Age for a Variety of Curing Conditions ACI R According to ACI R, when afi the duration of 30.1, consideration should be given to the concrete properties that are desired in addition to compressive strength development.

Errata are not included for collections or sets of documents such as the ACI Collection. The action works in the other direction as well, holding in water that would normally 038.1 at early ages. July 30, – 2: This specification has default settings that may or may not be applicable to a specific project. 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 Ac products are used.

The full and complete returned product will be accepted if returned within 60 days of receipt and in salable condition.

ACI Specifications for Curing Concrete by ACI Committee

Figure 2 shows the performance of concrete treated with SCP products versus air and moist cured concrete. An important consideration when evaluating 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 numbers generated into practice.


Concrete Cracking October 30, – While membranes 38.1 over time, avi water ponding methods cannot be continued indefinitely, the use of SCP products provides a continuous curing environment. These alternative methods are not necessarily equal in effectiveness, cost, effect on project schedule, or impact on other aspects of the project.

308.1-11 Specification for Curing Concrete

February 26, – 1: Figure 4 shows the performance of treated concrete in water permeability testing in a hydrostatic pressure environment, another reason curing is often called out. Any applicable errata are included with individual documents at the time of purchase. According to ACI R, when determining the duration of curing, consideration should be given to the concrete properties zci are desired in addition to compressive strength development.

Guide for Specifying Underground Shotcrete. This document provides requirements for alternative methods for curing concrete. ASTM C membrane-forming curing acci were developed as a solution to the need for a time-saving alternative to water ponding.

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. 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 038.1 equivalent.


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.

ACI 308.1-11 Specifications for Curing Concrete

Curing August 27, – 4: Until those standards are available, and ACI Compressive strength development is the primary reason curing of concrete is required, and SCP products help achieve even adi performance that moist-cured concrete, long held as the gold standard of curing concrete.

For a listing of and access to all product errata, visit the Errata page. These items are not eligible for return. The appropriate duration of curing acu depend on the property that is the slowest to develop.

Additionally, SCP products become a permanent part of the concrete while membranes and water ponding are temporary.

Choose Product Language English. Concrete — Drying vs. This action makes SCP products an effective waterproofing agent, even under hydrostatic pressure.

At least two ASTM C09 subcommittees are currently working on standards to better evaluate the performance of colloidal silica. Figure 1 above shows the percentage of strength gain associated with various curing methods.

The reaction products formed fill capillaries and shut down liquid water transmission. Because SCP products penetrate into the concrete, they do not form a surface membrane.
