ON THIS EPISODE OF THE CONCRETE LOGIC PODCASTWhat happens when a concrete mix designed to meet sustainability goals starts producing cracks and low strength breaks?Dr. Jon Belkowitz of Intelligent Concrete returns to discuss a contractor’s concern about a specification requiring significant cement replacement with fly ash.Jon explains why he believes changes in fly ash sourcing and processing deserve closer scrutiny. He connects residual carbon and added chemistry to potential changes in water demand, admixture performance, and bleeding, while acknowledging that the reported problems require investigation before assigning blame.Seth pushes for earlier contractor and producer involvement and more flexibility in specifications. Jon challenges whether a global warming potential limit can allow that flexibility when it indirectly restricts cement content.The conversation raises a practical question: Do you understand the materials going into your concrete, or are you relying on what the specification calls them?WHAT YOU’LL LEARNWhy cracking and low breaks alone do not establish fly ash as the causeHow Jon describes the shift from freshly collected fly ash to reclaimed sourcesWhy changing fly ash sources deserves another look at the concrete mixHow residual carbon can affect water demand and admixture performanceWhy bleeding and evaporation matter to finishing and early crackingHow Class C and Class F fly ash differ in their reactionsWhy Jon challenges the approach behind ACI 323Where Seth and Jon disagree about carbon limits and performance specificationsHow earlier contractor and producer involvement can expose conflicting requirementsWhy reducing concrete quantities and avoiding wasted loads belong in the carbon conversationCHAPTERS (01:10) Cracking, low breaks, and sustainability goals (02:16) Supporting the podcast and Concrete Logic Academy (05:59) The contractor’s fly ash problem (07:58) What fly ash is and why it was used (12:56) Reclaimed fly ash and a changing supply (17:04) Why fly ash source changes matter (19:40) Water demand, admixtures, and bleeding (22:41) Class C versus Class F fly ash (25:03) Investigating possible causes before assigning blame (30:18) Jon’s challenge to carbon requirements and ACI 323 (34:25) Carbon limits and performance specifications (37:23) Reducing concrete quantities and avoiding waste (40:23) Know what you’re putting in your concrete (40:45) Connecting with Dr. Jon Belkowitz GUEST INFODr. Jon Belkowitz Intelligent ConcreteGuest link: https://www.concretelogicpodcast.com/guests/dr-jon-belkowitz/CONCRETE LOGIC ACADEMYYour concrete materials are changing.

ON THIS EPISODE OF THE CONCRETE LOGIC PODCASTWhat does it take to build the process area of a massive LNG facility?Seth talks with Joey Goscha of Baker Construction about the concrete work behind the liquefaction trains, power facilities, and underground systems. Joey explains why the job starts with the ground and why early decisions can affect everything that follows. Seth presses him on pile connections and what happens when the work in the field does not go as planned. They also discuss how crews manage concrete production, safety, and quality at a pace few commercial contractors ever see.WHAT YOU’LL LEARNWhat the process area includes beyond the LNG storage tanks Why Gulf Coast ground conditions shape the work from the start How precast piles support massive equipment foundations Why Joey believes owners should invest in a thorough test pile program What can happen when pile connection sleeves miss their intended elevation How foundations are prepared for modules built elsewhere and shipped to the site Why crews place much of the structural concrete at night How multiple batch plants supply different mixes across the site Where precast and cast-in-place duct banks each make sense Why Joey puts safety first when discussing schedule and productivity What would surprise a commercial contractor walking onto an LNG project CHAPTERS (01:45) Introduction and ways to support the show (04:26) What is LNG, and why does it matter? (08:41) What goes into an LNG process area? (10:53) The size of the site and its workforce (12:13) Ground stabilization, piles, and foundations (17:12) Pile connections and the case for test piles (20:52) Night pours and concrete production (24:25) Miles of duct banks, piping, and trenches (27:04) Safety and productivity at this scale (29:28) Why stabilizing the ground is harder than it looks (33:00) What would shock a commercial contractor? (35:11) Joey on the pace of American constructionGUEST INFOJoseph “Joey” Goscha Vice President, Baker ConstructionGuest link: https://www.concretelogicpodcast.com/guests/joseph-goscha/ CONCRETE LOGIC ACADEMYGround conditions, pile decisions, mix coordination, and placement all affect what happens next.

VISIT CONCRETESCHOOL.CO TO START LEARNING TODAY.ON THIS EPISODE OF THE CONCRETE LOGIC PODCASTWhat if the product you bought as colloidal silica is actually a cheap silicate?Seth is joined by Dr. Jon Belkowitz of Intelligent Concrete to explain why these similarly named materials are not the same.Jon argues that pH is one of the quickest ways to distinguish colloidal silica from a silicate, and that the difference can affect performance, handling, specifications, and cost.The bigger concern is what happens when a product is sold as colloidal silica but is actually a much less expensive silicate. Jon says buyers should verify the chemistry instead of relying only on labels or sales claims.The conversation also connects colloidal silica to current durability concerns in concrete and asks a practical question: Are you actually getting the material you think you are buying?WHAT YOU’LL LEARN • The basic difference between a silicate and colloidal silica • Why Jon compares the difference between silicate and silica to the difference between cement and concrete • How sodium, potassium, and lithium silicates differ • Why pH can be an important first check when evaluating a product sold as colloidal silica • Why higher-pH silicates can require different handling and shipping considerations • Why the cost difference between silicates and colloidal silica matters when evaluating a product • Why Jon believes some products are being represented inaccurately in the marketplace • What DOTs, contractors, and owners should verify instead of relying only on product descriptions • Why Jon connects the renewed interest in colloidal silica to durability concerns with some lower-carbon concrete systems • How colloidal silica may be used as one tool for improving concrete performance • Why a certificate of analysis or independent testing can help confirm what material was actually suppliedCHAPTERS (00:00) Introduction and support for the show (02:13) A quick detour into Leon Foucault and science (02:50) Concrete Logic Academy and today’s topic (03:18) Silica versus silicates (04:59) Using pH to tell the difference (05:59) When does the difference matter in concrete?
