通过试验对比,熟悉各种早强减水剂的应用性能,确定消泡剂的种类和掺量。采用有机硅型消泡剂,掺量0.05%,含气量降低至1.8%,脱模强度达到设计强度的55%。为管片生产提供技术支持和质量保证。 Through the test comparison, familiar with the application of various early strength water reducer performance, to determine the type and amount of defoamer. The use of silicone defoamers, the amount of 0.05%, gas content decreased to 1.8%, the mold release strength of 55% of the design strength. For the production of pipe pieces to provide technical support and quality assurance.
