This paper reports on a study of waste clay brick that was ground and used as a supplementary cementitious material (SCM) in a mortar. The effect of this ground brick, in comparison with other conventional pozzolanic materials (namely, a Class F fly ash, and a natural pozzolan), on the alkali-silica reaction (ASR) of the mortar was evaluated. The ground clay brick, fly ash, and natural pozzolan were introduced into the mortar as a cement replacement at a 20 or 35% level. Fly ash-natural pozzolan and fly ash-ground clay brick combinations were also employed as a cement replacement at a 35% level. These SCM-incorporated mortar samples were tested for ASR expansion, flexural and compressive strength, and rapid chloride permeability. The test results indicate that all the SCMs considered in this study reduced the mortar ASR expansion, rapid chloride permeability, and the ASR-associated strength loss. The finely ground waste clay brick demonstrated high potential to reduce the ASR expansion as well as the ASR-associated strength loss.

Long-term mechanical properties of cellulose fibre-reinforced cement mortar with diatomite Ince, Ceren; Derogar, Shahram; Ball, Richard James; Ekinci, Abdullah; YÜZER, Nabi (Thomas Telford Ltd., 2019-09-01) This paper presents a study investigating the long-term mechanical properties of cellulose fibre-reinforced cement mortars incorporating diatomite as a replacement material for quartz sand. Important properties including mass, compressive and flexural strength, sorptivity, water penetration depth and porosity have been rigorously investigated. Significant findings demonstrated that increasing the replacement level of diatomite resulted in a systematic decrease in the final mass of cellulose fibre-reinforced...
Prediction of Elastic Moduli Development of Cement Mortars Using Early Age Measurements Deniz, Saygin; Erdoğan, Sinan Turhan (American Society of Civil Engineers (ASCE), 2015-01-01) This paper presents an investigation of the time development of dynamic and static elastic moduli of eight mortars made using CEM I cements with contrasting properties. Mixing and the preparation of dynamic testing prism specimens conformed to European standards. A nonstandard specimen and bending test setup was devised for measuring the development of a static Young's modulus. It was determined that dynamic Young's moduli determined using an ultrasonic pulse velocity test are often, but not always, greater...
Properties of blended cements with thermally activated kaolin Arikan, Metin; Sobolev, Konstantin; Ertuen, Tomris; Yeginobali, Asim; Turker, Pelin (Elsevier BV, 2009-01-01) Kaolin, one of the materials of major importance for the ceramic and paper industry, is also used in the construction industry as a raw material for the production of white cement clinker and, in the form of metakaolin, as an artificial pozzolanic additive for concrete. Metakaolin is a vital component of high-performance and architectural concrete; however, its application in regular concrete is very limited due to relatively high production costs. This report evaluates the performance of a low-cost metakao...
Comprehensive Evaluation of AIMS Texture, Angularity, and Dimension Measurements Mahmoud, Enad; Gates, Leslie; Masad, Eyad; Erdoğan, Sinan Turhan; Garboczi, Edward (American Society of Civil Engineers (ASCE), 2010-04-01) Aggregates are the most widely used construction materials in the world in structures built from both asphaltic and portland cement concrete composites. The performance of these composites is affected by aggregate shape characteristics (e.g., angularity, texture, and dimensions). The aggregate imaging system (AIMS) is a computer automated system that was developed to measure aggregate shape characteristics using digital camera images of aggregates. This paper addresses four issues concerning AIMS measuremen...
Effect of Presoaked Expanded Perlite Aggregate on the Dimensional Stability and Mechanical Properties of Engineered Cementitious Composites KESKİN, SÜLEYMAN BAHADIR; Sulaiman, Kamaran; Sahmaran, Mustafa; Yaman, İsmail Özgür (American Society of Civil Engineers (ASCE), 2013-06-01) This paper reports on an investigation of the use of expanded perlite aggregate as saturated lightweight aggregate (LWA) with respect to the mechanical and dimensional stability properties of engineered cemetitious composites (ECC). Expanded perlite aggregate was soaked in water for 24 h before its use in ECC, and replaced 10, 20, and 30% of the aggregate that was used in ECC production. The mixture proportion of a standard ECC mixture with properties that have been extensively reported in the literature is...
