Foam Drainage Analysis Method (Complete Test Video)
Просмотров 232Год назад
This video shows step wise procedure for conducting foam drainage analysis. This test is useful for understanding the effectiveness of air-entrainment admixtures (AEAs) with respect to the stability of developed air-system before using AEAs in the cementitious mixtures. The test can also be used in the presence of other chemical admixtures and supplementary cementitious materials (SCMs).

    • @LearningCorridorBharathMS
      @LearningCorridorBharathMS 2 месяца назад

      You do not necessarily need calcium carbonate solution to perform sorptivity test on any cementitious systems. All you need is tap water in accordance with ASTM C1585 standard as demonstrated in this video. I believe there is a South African standard for water sorptivity of cement mortar and concrete that makes use of lime water.

    • @LearningCorridorBharathMS
      @LearningCorridorBharathMS 3 года назад

      That’s a very good question, Pratik. For instance, for the overlays, depending on the overlay type (epoxy overlay, uhpc overlay etc.,), different state/central agencies (such as state Department of Transportation) have specified the limiting or the safer values. You can also get such values from already published papers/literature. [for example: If you are interested in a particular value, many of the overlay types have a overlay-to-substrate bond strength limit of 250psi].

    Hello, did you find the proper literature for the angular distribution of the BSE when tilting the sample? I am using a 4 quadrant detector and try to elaborate on surface tilt angle for using method c) shadow-bse to reconstruct a full 3d modell. However it is hard to find the edge when cosine lambert distribution is tipping over to forward scattering direction. I have found so many different values, over 30° tilt it will get away from lambert, another one says bow 60° to assume lambert is ok. Do you know any citation, or have more in depth knowledge about tilted surfaces and bse angular distribution? Thanks for your time to make this nice video.

    • @LearningCorridorBharathMS
      @LearningCorridorBharathMS 2 месяца назад

      Hi Raphael. Very good catch and a very good question. My focus during this work was in fact to develop and analyze UHPC mixes with and without fibers in the lab conditions. This was intended to specifically the air entrapment issues under different mixing conditions and parameters. A good or a bad workability is contextual and it is specific to the desired end application (for example, as an UHPC overlay material or as flowable concrete for accelerated bridge construction and pouring in construction joints). A good workability can be understood via flow tests on UHPC mixes and a flow of 7-10 inches indicates good workability. You can learn more from the following link probably: www.fhwa.dot.gov/publications/research/infrastructure/structures/14084/14084.pdf
