Prediction of early heat of hydration of plain and blended cements using neuro-fuzzy modelling techniques

In this study, a new approach based on an adaptive neuro-fuzzy inference system (ANFIS) was presented for the prediction of early heat of hydration of plain and blended cements. Two different type of model is trained and tested using these data. The data used in these models are arranged in a format of five input parameters that cover the additives percentage (AP), grinding type (GT) and finesses of cements (FC) and an output parameter which is heat of hydration of cements (HHC). The results showed that neuro-fuzzy models have strong potential as a feasible tool for evaluation of the effect of additives percentage, grinding type (GT) and finesses of cements on the early heat of hydration of cements. Some conclusions concerning the impacts of features on the prediction of early heat of hydration of plain and blended cements were obtained through analysis of the ANFIS. The results are highly promising, and a comparative analysis suggests that the proposed modelling approach outperforms ANN model in terms of training performances and prediction accuracies. The results show that the proposed ANFIS model can be used in the prediction of early heat of hydration of plain and blended cements.

Insulation properties of bricks made with cotton and textile ash wastes

Abstract Huge amounts of cotton and textile ash waste are disposed of by countries all over the world. The majority of cotton wastes and textile ash wastes is expelled in such a way as to cause serious environmental problems. The present study involves experimental research investigating the potential use of cotton and textile ash wastes combination for producing a new and lightweight composite building material with good insulation properties. The results showed that the cotton and textile ash waste bricks fulfill the compressive strength and heat conductivity requirements of the ASTM and Turkish Standards. A cotton and textile ash waste brick house has been found to be superior to a concrete brick house for regulating indoor temperatures. The production process can be easily applied in conventional brick plants. The product is a light weight composite which can be used for making bricks and wall and ceiling panels with good insulation properties.

The use of fly ash and basaltic pumice as additives in the productionof clay fired brick in Turkey

Abstract The main objective of this study is to investigate the suitability of fly ash and basaltic pumice as additives in the production of high quality clay fired bricks. Clay bricks with/without additives were produced adding equal amounts of fly ash and basaltic pumice, separately and together, with the rates of 5, 10 and 20 wt.%. Each sample was fired at 700, 900 and 1 050°C for 8 h. Bulk density, harmful magnesia and lime, shrinkage, water absorption, compressive and flexural strength, freezing and thawing tests were carried out. The test results were compared with the standard values and they were found to be satisfactory. Finally, it was concluded that both fly ash and basaltic pumice were suitable admixtures and could be used efficiently in fired brick production.

Microstructure of red brick dust and ground basaltic pumice blended cement mortars exposed to magnesium sulphate solutions

This paper presents a laboratory study on the deterioration of blended cement combinations of plain Portland cement (PPC) with red brick dust (RBD) and ground basaltic pumice (GBP). The compressive...

An environment-friendly thermal insulation material from sunflower stalk, textile waste and stubble fibers

Heating costs in winter and in summer cooling costs in the world is very high. To reduce heating costs in winter and cooling costs in summer are building insulation. Although sunflower production in Turkey carried out a significant amount, however they emerged after the production of sunflower stem is a serious problem for farmers. Sunflower stem from farm houses to be cleaned or burned or used for temporary heating purposes. This type of use is causing serious problems in the environment. Sunflower stalk, cotton textile waste, such as stubble, and a composite material produced by evaluating the landfill waste. This is considered to be important in terms of heating costs. TS 825 predicted to be material factor insulation than 0.1 must be in small. In press load increase, a portion of the linker and an amount of escaping out of the connector in the mold with respect to the binder mixture dragging causes impoverishment and the binder being dropped. Set out in the findings, research materials selected sunflower stalk, cotton - textile wastes and stubble shows that it is possible to produce insulation materials enough to mix it with epoxy.

The use of ground silica sand, ground granulated blast furnace slag and ground basaltic pumice in cementitious adhesives for tiles

Abstract The aim of this study was to use ground silica sand, ground granulated blast furnace slag and ground basaltic pumice in the production of adhesives for tiles. The main purpose was to improve the durability of adhesives. Furthermore, an investigation was carried out to determine adhesive resistance to aggressive conditions. The study examines the effects of acids, shrinkage and freezing thawing cycles. The results showed that the adhesives were prepared and applied easily due to improved initial adhesion. The durability improvement can be explained by the low water absorption and high permeability. All specimens were observed to fulfill the shear and tensile adhesion strength requirements of both European and Turkish Standards.
