In this study, the fresh properties of self-compacting concrete (SCC) incorporating ground waste glass (GWG) as cementing material were experimentally investigated. GWG was used as a partial replacement for cement at replacement levels of 0, 5, 10, 15, 20, 25 and 30% by weight. Reducing the consumption of cement in construction is a major issue in terms of economic performance. Such reduction would also contribute to the environment by lessening the harmful impact of the manufacturing process. Concrete mixtures containing different levels of GWG were prepared with the water to cementitious materials ratio of 0.51. The examined properties included workability, wet density, air content and setting time. Workability of the fresh concrete was determined by using the slump flow, visual stability index, V-funnel, J-ring, L-box and GTM screen stability tests. The results indicate that there is a slight decrease in the wet density of self-compacting ground waste glass concrete (SCGWGC) of nearly 1.37% with the increase of GWG content. The conclusion is that using GWG significantly increases the workability of SCC mixtures. As the GWG increases, the slump flow also increases at a constant amount of water and super-plasticizer, but the concrete flow time decreases. The results showed that it is possible to successfully produce SCC with GWG as cement replacement.

“…Bu nedenle, KYB'ler yüksek fırın cürufu, uçucu kül ve kireç tozu gibi ince parçacıkların büyük miktarlarını içerir. KYB'de ince parçacıkların kullanılma sebebi ise taze karışımda daha büyük parçacıkların ayrışmasını önlemektir [4][5][6].…”

ÖZBu çalışma kendiliğinden yerleşen beton (KYB) üretiminde Osmaniye bazik pomzasının işlenebilirliğe olan etkisini araştırmak amacıyla gerçekleştirilmiştir. Bazik pomza katkılı kendiliğinden yerleşen beton (KYBB) üretimi 0,32 sabit su/bağlayıcı (çimento + uçucu kül) oranında, 690±20 mm sabit bir çökme akışıyla, yüksek oranda su azaltıcı katkı (akışkanlaştırıcı) kullanılarak gerçekleştirilmiştir. İlk olarak bazik pomza hiç katılmaksızın kontrol betonu sabit su/bağlayıcı oranı ile dökülmüş ve daha sonra bazik pomza %20, %30, %40, %50 ve %60 oranlarında her defasında iri agreganın yerine ikame edilerek karışıma eklenmiştir. Bazik pomzanın KYBB'lerin taze ve sertleşmiş haldeki özellikleri üzerine etkilerini tespit etmek amacıyla taze haldeki betonun çökme yayılma tablasında akış çapı ve T 500 süresi, V hunisinde boşalma süresi, L kutusunda yükseklik oranı testleri ve 28 günlük basınç dayanımı testi yapılmıştır. KYBB'de kullanılan bazik pomza miktarı arttıkça işlenebilirliğin giderek azaldığı tespit edilmiştir. Bu nedenle en fazla %60 oranında bazik pomza kullanılarak KYBB üretilebilmiştir. KYB'nin basınç dayanımı ise bazik pomzanın özgül ağırlığının kırma taştan düşük olmasından dolayı %23 oranında bir azalma göstermiştir.Anahtar Kelimeler: Bazik pomza, kendiliğinden yerleşen beton, taze özellik EFFECT OF BASIC PUMICE ON THE WORKABILITY CHARACTERISTICS OF SELF-COMPACTING CONCRETES ABSTRACTThis study has been carried out to investigate the effect of Osmaniye basic pumice on the workability characteristics of self-compacting concrete (SCC). Self-compacting concrete incorporated basic pumice (SCCB) with a constant water / binder ratio (cement + fly ash) of 0.32 was produced at a fixed slump flow diameter of 690±20 mm by adjusting the amount of High-Range-Water-Reducing-Admixture (HRWRA). First, control concrete without basic pumice was produced at a constant water/binder ratio and then basic pumice replacing the coarse aggregate in the proportions of 20%, 30%, 40%, 50% and 60% was added to the mixture. To identify effects of basic pumice on properties in the fresh and hardened state of SCCB, slump flow diameter, T 500 flow time, V-funnel flow time, L-box height ratio and 28-day compressive strength tests were conducted. Increasing amount of the basic pumice in the SCC resulted in a gradual decrease of workability. Therefore, SCCB has been manufactured by adding basic pumice up to 60%. Due to the specific weight of basic pumice lower than that of crushed stone, compressive strength of SCC showed a decrease of 23%.

“…1 PhD., University of Technology Sydney, Faculty of Civil and Environmental Engineering, Sydney, NSW, Australia, In recent decades, utilizing the mineral and chemical admixtures in concrete technology has introduced several changes in formulation and mix design to make the concrete workable, stronger and durable. [12] LWSCC as a combination of Light Weight Concrete (LWC) and SelfCompacting Concrete (SCC) is a result of advances in concrete technology to come over the limits in concrete structures. Using LWC may result in smaller dimension and lighter elements that both decrease the total weight of the structure and the lateral loads that is a major problem in most parts of the world.…”

“…Using LWC may result in smaller dimension and lighter elements that both decrease the total weight of the structure and the lateral loads that is a major problem in most parts of the world. [12,13] It is naturally utilized in structures for which major part of the total load is due to dead load weight of concrete. Consequently, the construction cost can be protected when applied to structures such as long span bridge and high rise buildings [14].…”

“…Consequently, the construction cost can be protected when applied to structures such as long span bridge and high rise buildings [14]. In addition, better thermal insulation; better reinforcing steel-concrete bond, durability performance, tensile strain capacity, and fatigue resistance make it superior to normal weight concrete [12,14]. In conjunction with the density of concrete; workability, strength, and durability are major considerations in concrete application in construction industry.…”

Light-weight Self-Compacting Concrete (LWSCC) might be the answer to the increasing construction requirements of slenderer and more heavily reinforced structural elements. However there are limited studies to prove its ability in real construction projects. In conjunction with the traditional methods, artificial intelligent based modeling methods have been applied to simulate the non-linear and complex behavior of concrete in the recent years. Twenty one laboratory experimental investigations on the mechanical properties of LWSCC; published in recent 12 years have been analyzed in this study. The collected information is used to investigate the relationship between compressive strength, elasticity modulus and splitting tensile strength in LWSCC.Analytically proposed model in ANFIS is verified by multi factor linear regression analysis. Comparing the estimated results, ANFIS analysis gives more compatible results and is preferred to estimate the properties of LWSCC.
