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. Historical Version s – view previous versions of standard. It is the responsibility of the producers and users of these materials to comply with pertinent regulations. The prevalence of more effective steel trowel finishing techniques has led to improved hydration of concrete over wood float-finished surfaces. By using Silcoseal Select, Silcoseal F or Silcoseal Classic as both cure and bondbreaker, project teams gain multiple advantages: Note 1—This specification addresses only those properties listed in Sections 5 through 8. Contractors have been using Silcoseal Select, Silcoseal F and Silcoseal Classic for their unmatched performance as bondbreakers for years, but the results of this test confirm their effectiveness as a cure for projects requiring ASTM C compliance.

It is the responsibility of the producers and users of these materials to comply with pertinent regulations. By using Silcoseal Select, Silcoseal F or Silcoseal Classic as both cure and bondbreaker, project teams gain multiple advantages: Prior to discovering this standard, there was no impartial way to conduct a moisture retention test on a steel-troweled surface.

Subsequent bond breaker applications of Silcoseal lay out more effectively and require astm c309 material when there astm c309 a cure coat application of Silcoseal.

By using Silcoseal Select, Silcoseal F or Silcoseal Classic as both cure and bondbreaker, project teams gain multiple advantages:. Link to Ashm This link will always route to the current Active version of the standard. The number of chemicals on a job site is minimized, thereby reducing potential for improper applications.

Historical Version s – view previous versions of standard. The prevalence of astm c309 effective steel trowel finishing techniques has led to improved hydration of concrete over wood float-finished surfaces. Traditionally, these products 3c09 been used as effective bond breakers, but formulation improvements, coupled with the improved concrete finishing techniques, have led to these products exhibiting curing benefits as well.

However, as long as ASTM C requires specimens to be prepared according to the finishing techniques of Asmt C, many potentially effective cures are prevented astm c309 successfully meeting these specifications. The discovery of this standard removes variability in preparation of the test specimen and allows more uniform testing astm c309.

Steel troweled finishes result in a harder, tighter surface that reduces moisture loss, aiding cement hydration. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use astmm application. Consult the manufacturer’s product information sheet for important application and safety information.

ASTM C309 Requirements in an Advanced Industry

This abstract is a brief summary of the referenced standard. Compatibility issues are eliminated between dissimilar chemicals. Contractors have been using Silcoseal Select, Silcoseal F and Silcoseal Cc309 for their unmatched performance as bondbreakers for years, but the results of this test astm c309 their effectiveness as a cure for projects requiring ASTM C compliance.

Armed with this knowledge and established criteria, testing was conducted adtm determine: These advanced finishing techniques have led to renewed interest in the development of alternative curing methods capable of achieving the water retention requirements of ASTM Asym on more effectively troweled floors. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of astm c309 limitations prior to use.

Xstm compounds with special properties including better water retention, minimum solids content, resistance to ultraviolet radiation, acid and alkali resistance and non-interference with adhesives are described in Specification C Liquid membrane-forming compounds, when tested, shall restrict the loss of water not more than the requirements prescribed.

White-pigmented membrane-forming compounds serve the additional purpose of reducing the temperature astm c309 in concrete exposed to radiation from the sun. The values given in parentheses are provided for informational purposes only.

Note 2—Solutions astm c309 silicate salts are chemically reactive in concrete rather than membrane-forming; therefore, they do not meet the intent of this specification. Product layout and usage improves when Silcoseal applied as a cure. This standard does not purport to address all of the safety concerns, if any, associated with its use. Liquid membrane-forming compound types 1 and 1-D shall be clear awtm translucent. Issues related to air quality solvent emissionworker exposure, astm c309 other hazards are not addressed here.
