Effects of dry particle coating with nano- and microparticles on early compressive strength of portland cement pastes
(Tulpar Academic Publisher, 2021)
It is known that nano-and microparticles have been very popular in recent years since their advantages. However, due to the very small size of such materials, they have very high tendency to agglomeration particularly for ...
Green building envelope designs in different climate and seismic zones: Multi-objective ANN-based genetic algorithm
(ELSEVIER, 2022)
In recent years, the major component of green building designs adopted by governments in order to reduce CO2
emissions as well as energy consumption is the green building envelope. The green envelope has the most
important ...
Role of inclusion size distribution of titanium dioxide on the nitrogen oxides reduction capability and microstructural characteristics of cementitious systems
(ELSEVIER SCI LTD, 2022)
This paper explores the effect of the inclusion size of titanium dioxide (TiO2) particles on a variety of performance properties of cementitious systems via experimental studies. In addition to comprehensive microstructu ...
Compatibility of Superplasticizers with Limestone-Metakaolin Blended Cementitious System
(SPRINGER, 2015)
This study investigates the performance of polycarboxylate ether (PCE), polymelamine sulfonate (PMS), sodium lignosulfonate and naphthalene formaldehyde condensate (PNS) superplasticizers (SPs) with ASTM C595 Type IL cement ...
Characteristics of calcined natural zeolites for use in high-performance pozzolan blended cements
(ELSEVIER SCI LTD, 2014)
Two natural zeolites with different characteristics were calcined at various temperatures in order to
improve the benefits provided by their use in blended cements as cement replacement material. Natural
zeolites were ...
Reaction kinetics and properties of pumice-based geopolymer systems cured at room temperature
(ELSEVIER, 2023)
This research investigated the kinetics of pumice-based geopolymer systems and their physical and mechanical
properties. The effect of the Na2SiO3/NaOH ratio of geopolymer systems on the rate of heat evolution and total
heat ...
Effect of duration and type of grinding on the particle size distribution and microstructure of natural pumice with low pozzolanic reactivity
(ELSEVIER, 2023)
Pumice, with low pozzolanic reactivity, was ground for 1, 3, and 6 h with a laboratory ball mill in dry conditions and it was ground for 1 h in wet conditions via an industrial-scale ball mill. Based on derivative particle ...
Effect of characteristics of natural zeolites on their geopolymerization
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)
The properties of clinoptilolite-based geopolymers are investigated with a focus on the parameters affecting the reactivity of clinoptilolite in a geopolymer binder. A complete characterization of raw materials was carried ...
Effect of mineralogical composition of clinoptilolite-bearing tuffs on their performance as a natural pozzolan in cementitious systems
(TECHNO-PRESSPO BOX 33, YUSEONG, DAEJEON 305-600, SOUTH KOREA, 2021)
In this study, pozzolanic reactivity and strength activity of zeolitic tuffs containing similar amount of zeolitic phase (clinoptilolite) and different types and amounts of impurities were examined in order to understand ...
Influence of nano SiO2 and nano CaCO3 particles on strength, workability, and microstructural properties of fly ash-based geopolymer
(ERNST & SOHN, ROTHERSTRASSE 21, BERLIN, DEUTSCHLAND 10245, GERMANY, 2020)
The influence of nano SiO2(NS) and CaCO3(NC) particles on the properties of class F fly ash based geopolymer mortar activated with different sodium ion concentrations have been investigated. Mortar mixture proportions were ...
