  We are getting more in depth about our HRWR dosages in Illinois. Specifically we are seeing what HRWR naphthalene lignin poly carboxylate and its effect on Air entrainment in concrete. I know this is diverse and vague explanation but do you have any information on this? You talk about so many different aspects in this series but do you properly cover air entrainment and the effects of HRWR on Air Entrainment?

  Valid question. A lot of folks are having problems stabilizing air in concrete. A lot of manufacturers are seeing this due to an increase in dirtiness of sand, change in cement chemistry as well as change in admixture chemistry. Over the last 5 years, the raw materials for both HRWRs and MRWRs have changed in quality and volumes. This has lead to a manifold of issues to include a stabilization of the air entrainment. We can put together a show going over this in more detail. Thanks for the question.

  On a deep dive into concrete topics late at night, I’ve been curious about the practical effects of high-range water-reducing (HRWR) admixtures on air entrainment, especially when using the pressure method for on-site air tests. What factors cause the test results to 'jump,' leading to lower air dosages at the plants as a precaution? I understand that the defoamer plays a huge part but essentially why do we see low specific surface and spacing factor results that don't align with the on-site air test outcomes? Essentially, we need the same series, but focused on types of air entrainment, their importance, and how the effects vary based on the mix. START THE VLOG BACK UP!

  - why do we see “air jumps” at the plant? + we literally had this conversation all of last week. Air jumps can be caused by a lot of things - our recent chat focused on a change in the dirtiness of sand how the air went from 2% to 11% with the same dosage (2 fl oz per cwt). What I would do in this situation is an “elimination diet” with your mixes - find out the cause first. If indeed it is your HRWR, that is not unheard of, check to see if your reformer has separated from the HRWR. It normally can be seen floating on top of the tank of HRWR. I have a picture of what it looks like and will include it in the video. This happened to me years ago at a plant in New Mexico and Colorado. It happens. Finally, I hate to add this but… are you using the hardened air void analysis or the SAM? That SAM as much as I like it can be a pain to calibrate. I would double check the SAM make sure everything is good - it could be a calibration thing too.

  I’m assuming your mixes containing colloidal silica are made using liquid colloidal silica additive? Can you get the same results using dry powder like silica fume (cabosil)? From my understanding of making a good clay body in ceramics, particle size distribution plays a huge role in strength of final product. Is the colloidal silica in concrete helping with the particle size distribution on the very fine end, and adding strength because of that? Or is it some other property of the colloidal silica?

•

  There a lot of properties we get out colloidal silica: instantaneous pozzolanic reaction, accelerated cement dissolution, particle to particle packing and more. You could get similar benefits from silica fume and the like all be it not to the degree.

  I have come to the conclusion through yrs of experience steel cooks top surface causing faster setting time of top surface creating a void or seperation from bottom portion of concrete top has such faster setting time when a cure and seal is used i believe this allows a chance for bottom portion to pull top portion together have a sealed barrier preventing massive water loss from top portion

  Just like pump mix. She’s got the lube! I’ve got a few questions 1. What causes concrete to flash set? 2. What’s the difference between hydration stabilizer and retarder? 3. Do you think brown sugar is more potent than white sugar for killing concrete. Thank you good sir, I love your channel

• 
  @IntelligentConcrete2 ай бұрын

  Thank you!!!! Here are the answers, let me know if you babe any other questions. 1. Flash set is normally due to a lack of gypsum added during the manufacturing process. Without the correct type or smith of gypsum the cement hydration process can take off like a bat out of hell. 2. A “set retarder” should only impact the fresh properties by delaying the concrete setting (initial, 500 psi and final, 4000 psi). Meaning if you don’t have enough finishers on the jobsite, the set retarder will delay set time to give you more room to level and close up the concrete surface before you need to do final finishing operations. A “hydration stabilizer” is designed to counteract anything that will accelerate the hydration process. We normally used them as part of a “Fast track pavement” and “mass concrete.” Where we put a lot of accelerators in the mix but wanted to stabilize the reaction until enough cement has dissolved and we can maximize earl strengths - FTP. And to reduce the heat build up in mass concrete that could causes internal temperatures to build up to high and cause cracking.

  @MrOliverAC2 ай бұрын

  I understand that clear benefits, but every time I see pervious concrete slabs, it is full of cracks and settlements. It seems to me that the same water that leaks through the aggregate also washes of the soil that supports the concrete, therefore settling it. And if it needs replacement in few years because of that, then it seems like it's more eco-friendly to built with regular non-pervious concrete. What do you guys think?

• 
  @IntelligentConcrete2 ай бұрын

  Settlement is usually a fault of the subgrade - base course. I think it all depends where you are willing to invest resources and what the objectives are for the project. Sometimes, pervious is a really expensive slab. Nothing more.

  A quick clarification question. One method says: “Prior to mixing the test material, the mixer should be “buttered” using aggregates and a non-air-entraining cement other than that supplied by the cement and concrete reference laboratory.” I’m a believer of buttering the drum with a non-representative random mixture of mortar. The 3 levels of butter accuracy: 1. No butter bare drum. Pros: simple to do. Cons: paste + sand (Mortar) will be left in mixer. The final batch will have a higher coarse aggregate percentage than designed. Smaller batches will lose a larger percentage of their batch to coating the drum. 2. Random butter to coat drum. Pros: almost as simple as above(1). Theoretically no mortar should be lost from the buttered drum to after dumping out the mixed batch. Cons: cement+SCM’s+water+sand left in the mixer may not match the final batch proportions exactly. 3. Representative butter sample identical to that of the tested mix design. Cons: Much more complicated to get a mini-batch to the same slump & entrained air consistency as the final batch. It takes time to test & adjust even before completing the main test batch. Pros: Theoretically should be the most representative if the exact same raw constituents are used from butter to batch.

  For full experiment you had to reduce the amount of water on 3 and 4, just because you can. Maybe because it was too liquid, it separated the cement from sand.
