The course covers conventional SCMs (fly ash, slag cement, silica fume), natural pozzolans, harvested ash, and emerging alternative SCMs, including their pozzolanic chemistry, fresh and hardened concrete benefits, durability performance, and dosage practices. Students will gain the knowledge to evaluate SCM mix designs, apply specification frameworks, and navigate supply and material approval challenges in highway construction practice.\u003c\/p\u003e\n\u003ch4\u003eLearning Objectives\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eDefine supplementary cementitious materials and explain the pozzolanic reaction mechanism\u003c\/strong\u003e by which SCMs improve concrete strength, reduce permeability, and enhance durability in highway applications.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eIdentify the types of SCMs, natural pozzolans, and alternative SCMs\u003c\/strong\u003e used by state DOTs, including their classification under ASTM C618-23 and AASHTO M 295, and describe appropriate replacement rates for pavement and structural applications.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eDistinguish the durability benefits of binary, ternary, and quaternary SCM mixtures\u003c\/strong\u003e and explain how SCM use mitigates adverse reactions such as alkali-silica reactivity, sulfate attack, and chloride-ion penetration.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eAnalyze current state DOT specification practices and supply challenges\u003c\/strong\u003e related to fly ash availability, harvested ash, and ASCMs, and apply appropriate evaluation criteria when reviewing contractor mix design submittals.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Basepdh","offers":[{"title":"Default Title","offer_id":52231673315640,"sku":null,"price":30.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/basepdh.myshopify.com\/products\/supplementary-cementitious-materials-scms-in-modern-highway-construction","provider":"Basepdh","version":"1.0","type":"link"}
