We have tried to make it as much a self-study guide as possible. The book has been arranged in the order it will be presented in our schools.  \nIt should help serve as a source of information for the person starting in concrete work, as well as a reference book to those with considerable concrete construction experience. The objective is to train and educate so that the end results will be better quality concrete in the construction of our highways.  \nThe information included in this book is generally compatible with current specifications and instructions; however, it should not be considered a specification. It should be used only as a guide and as a reference to supplement the reader’s knowledge of concrete.  \nChristopher A. Peoples , P. E.  \nState Materials Engineer  \nNorth Carolina Division of Highways  \nACKNOWLEDGEMENTS  \nThe writers would like to express their appreciation to the following sources of information used in this book:  \nAmerican Concrete Institute  \nAmerican Association of State Highway and Transportation Officials  \nASTM International  \nNCDOT Standard Specifications for Roads and Structures (2012 edition)  \nPortland Cement Association  \nVirginia Department of Highways and Transportation  \nThe writers also express their gratitude to all personnel of the Department who assisted in the preparation of this study guide. Special thanks to the Department of Civil Construction and Environmental Engineering at NC State University.  \nTABLE OF CONTENTS  \nPreface--------------------------------------------------------------------------------- 2  \nAcknowledgement------------------------------------------------------------------- 3  \nNC DOT Pre-Exam---------------------------------------------------------------------- 6  \nNCDOT/ACI Examination Procedures and Requirements--------------------- 10  \nNCDOT /ACI Tests------------------------------------------------------------------ 12  \nSECTION I Components of Concrete-------------------------------------- 14  \nIntroduction--------------------------------------------------------------------------- 15  \nDesirable Properties of Concrete-------------------------------------------------- 14  \nConcrete Ingredients---------------------------------------------------------------- 16  \nPortland Cement------------------------------------------------------------ 16  \nFly Ash----------------------------------------------------------------------- 18  \nMixing Water---------------------------------------------------------------- 19  \nAggregates------------------------------------------------------------------- 20  \nAdmixtures------------------------------------------------------------------- 21  \nAlkali Silica Reactivity-------------------------------------------------------------- 25  \nStudy Questions: NCDOT Components of Concrete------------------ 26  \nSECTION II NCDOT Materials and Tests Letters and Policies---------- 32  \nNCDOT III (a)– Determining Air Content of Fresh Concrete Containing Marine Limestone and Lightweight Aggregate---------------------------------- 34  \nNCDOT III (b)– Making, Storing, Transporting Concrete Cylinders---------------------- 35  \nNCDOT III (c)– Minimum Sampling for Incidental and Structural Concrete------------ 40  \nSummary Chart: Minimum Sampling-------------------------------------------------- 43  \nNCDOT III (d)– Adding Air Entrainment Agent at the Job Site------------- 47  \nNCDOT III (e)– Concrete Mix Design New Numbering Scheme------------ 50  \nNCDOT III (f)– Instructions for Submittal and Acceptance of Concrete Mix Designs 5","cbCaiis0lWzln37y","https://ap.wps.com/l/cbCaiis0lWzln37y","pdf",16116294,155,"English","# Preface\n# Acknowledgement\n# NC DOT Pre-Exam\n# NCDOT/ACI Examination Procedures and Requirements\n# NCDOT /ACI Tests\n# SECTION I Components of Concrete\n## Introduction\n## Desirable Properties of Concrete\n## Concrete Ingredients\n## Portland Cement\n## Fly Ash\n## Mixing Water\n## Aggregates\n## Admixtures\n## Alkali Silica Reactivity\n## Study Questions: NCDOT Components of Concrete\n# SECTION II NCDOT Materials and Tests Letters and Policies","[{\"question\":\"这本学习指南的目标是什么？\",\"answer\":\"用于帮助技术人员、拌和机操作员、检查员以及承包商/生产方人员进行自学与备考，最终成为“Certified Concrete Field Technician”，并提升高速公路建设中的混凝土质量。\"},{\"question\":\"这些内容能否直接视为规范（specification）？\",\"answer\":\"不能。文中说明信息与现行规范与指令一般兼容，但不应被当作规范使用，只能作为指导与参考来补充读者的混凝土知识。\"},{\"question\":\"指南的内容结构大致包含哪些模块？\",\"answer\":\"包含混凝土组成（Section I）、NCDOT材料与检测相关信函/政策及测试信件（Section II）、NCDOT表格（Section III）以及现场试验程序与标准（Section IV），并配套学习题与术语定义（后续部分）。\"}]","Concrete Field Technician Study Guide - Materials & Tests Unit - NCDOT - July 2016 | PDF",1790334448,391]
