课程名称：混凝土技术文凭 – 成为混凝土技术专家 课程概述： 本课程旨在提供混凝土技术的全面知识，涵盖混凝土的成分、生产过程及其性能分析。课程分为三个模块。 模块1：混凝土成分 - 水泥：了解水泥的制造过程、减少碳足迹的步骤、化学成分及其重要性、水泥的水化过程和不同类型的水泥。包括水泥的测试。 - 粗细骨料：探讨细骨料的功能和要求，河沙的替代品以及M砂的介绍和制造；粗骨料的大小、形状和纹理的重要性，骨料的等级与混合，测试要求及再生骨料的使用。 - 水：水的质量要求。 - 化学混合物：包括塑化剂、加速剂、减缓剂和引气剂。 - 矿物掺合料：如火山灰、粒化高炉矿渣、硅烟、超细高岭土和稻壳灰等。 模块2：新鲜混凝土的可工作性 - 影响工作性的因素及其测量：包括下沉、压实系数和Vee-Bee一致性测试、流动测试。探讨分离和出水现象。 - 混凝土的生产过程：包括配料、混合、运输、浇筑和压实。养护方法：水养护、膜养护、蒸汽养护、加速养护和自养护。讨论新鲜混凝土的良好与不良实践及在大体积混凝土施工中的水化热影响。 模块3：混凝土配合比设计 - 探讨混合设计的概念，包括使用与不使用掺合料的设计。配合比中的变量和环境条件，配合比设计成分的选择标准，配合比设计流程。 - 采用IS-10262:2019进行配合比设计的数值示例。 总结： 本课程将深入探讨水泥、骨料及其他成分在混凝土生产中的作用，并研究新鲜和硬化混凝土的特性，以提高学员在混凝土技术领域的实践能力。
Syllabus of the Course Module-1 Concrete Ingredients Cement Concrete Ingredients Cement -Cement manufacturing process, steps to reduce carbon footprint, chemical composition and their importance, hydration of cement, types of cement. Testing of cement. Fine aggregate: Functions, requirement, Alternatives to River sand, M-sand introduction and manufacturing. Coarse aggregate: Importance of size, shape and texture. Grading and blending of aggregate. Testing on aggregate, requirement. Recycled aggregates Water - qualities of water. Chemical admixtures - plasticize-rs, accelerators, retarders and air entertaining agents. Mineral admixtures - Pozzolanic and cementitious materials, Fly ash, GGBS, silica fumes, Meta kaolin and rice husk-ash. 2. Module-2 Fresh Concrete WorkabilityFresh Concrete Workability-factors affecting work ability. Measurement of work ability-slump, Compaction factor and Vee-Bee Consistometer tests, flow tests. Segregation and bleeding. Process of manufacturing of concrete- Batching, Mixing, Transporting, Placing and Compaction. Curing - Methods of curing - Water curing, membrane curing, steam curing, accelerated curing, self- curing. Good and Bad practices of making and using fresh concrete and Effect of heat of hydration during mass concreting at project sites.3. Module-3 Concrete Mix ProportioningConcrete Mix ProportioningConcept of Mix Design with and without admixtures, variables in proportioning and Exposure conditions, Selection criteria of ingredients used for mix design, Procedure of mix proportioning. Numerical Examples of Mix Proportioning using IS-10262:2019.Concrete TechnologyConcrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Portland cement is the commonly used type of cement for production of concrete. Concrete technology deals with study of properties of concrete and its practical applications.The main items we'll focus on in this course are:Cement - Types & Roles of Different Ingredients Manufacturing of Cement - Dry & Wet ProcessThe influence of admixtures and aggregatesProperties of fresh and hardened concreteWork ability, settlement, bleeding and Segregation Production of Concrete
