Introduction

This CESP issue consists of papers that were submitted and approved for the proceedings of the 39th International Conference on Advanced Ceramics and Composites (ICACC), held January 25–30, 2015 in Daytona Beach, Florida. ICACC is the most prominent international meeting in the area of advanced structural, functional, and nanoscopic ceramics, composites, and other emerging ceramic materials and technologies. This prestigious conference has been organized by the Engineering Ceramics Division (ECD) of The American Ceramic Society (ACerS) since 1977.

The 39th ICACC hosted more than 1,000 attendees from 40 countries and over 800 presentations. The topics ranged from ceramic nanomaterials to structural reliability of ceramic components which demonstrated the linkage between materials science developments at the atomic level and macro level structural applications. Papers addressed material, model, and component development and investigated the interrelations between the processing, properties, and microstructure of ceramic materials.

Geopolymers and Chemically Bonded Ceramics

PROPERTIES OF GRANITE POWDER REINFORCED POTASSIUM GEOPOLYMER

Daniel S. Roper, Gregory P. Kutyla and Waltraud M. Kriven

University of Illinois at Urbana-Champaign, Department of Materials Science and Engineering, Urbana, IL 61801 USA

Granite powder is a waste product at many quarries and stone processing plants all over the globe. This waste powder, when properly sieved into an appropriate size distribution, can be used as a suitable reinforcement for geopolymers. The goal of this design was to create a sustainable, cost-effective and reliable structural geopolymer composite utilizing resources that are easily attained worldwide. Its properties and viability as a structural material were determined through four-point flexure testing according to ASTM standards and analyzed by Weibull statistics. Its refractory properties were tested by exposing samples to various temperatures, then testing for shrinkage and flexure strengths. Heat treatment of all samples yielded cracking and warping, but the coarse granite samples maintained strengths over 2 MPa while fine samples maintained 10 MPa strengths. Scanning electron microscopy (SEM) was used to characterize the size and geometries of the granite powder, and to determine its viability as a reinforcement for potassium geopolymer.

INTRODUCTION

Geopolymers are an inorganic polymeric structural material consisting of alumina, silica and an alkali metal oxide. This study used potassium hydroxide, mixed with water and fumed silica, to create potassium waterglass. When combined with metakaolin, this mixture became liquid geopolymer precursor. This liquid can be easily poured into molds of almost any shape, and can also accommodate a multitude of reinforcement options. Geopolymers are emerging as an environmentally-friendly alternative to ordinary cements, as they produce only about 20% of the carbon dioxide compared to that produced by the manufacturing of Portland cement, an industry that is responsible for 5% of the world’s carbon dioxide emission[1]. The abundance of all the materials needed to make effective geopolymers also creates the opportunity to eventually make bulk production of geopolymers cheaper than ordinary cements.

Geopolymers can be used with a wide range of reinforcements, including but not limited to metals, ceramics, and polymers[2]
