Abstract:
Dental polymer-based luting materials are classified into esthetic resin cement, adhesive resin cement and self-adhesive resin cement. Due to the different component of each type of resin cement, the preconditioning method of tooth surface and the steps are different from each type of resin cement. The pre-treatment of adherend (ceramic, resin and metal) surface also varies with the type of resin cement and the manufacturer. In this study, the characteristics of each type of resin cement, mechanical properties, indication and advantages were investigated. Through these, clinical tips on using

Abstract:
The cement efficiency or reactivity of two type GU cements sold in the southern Ontario market was studied using compressive strength measurements of concrete coupled with Abram's Law. At 28 days, it was found that there was a marked performance difference between the two cements. For example, at 28 days, the cement efficiencies were 0.0889 and 0.0953 MPa·kg 1. The difference in cement efficiency was related somewhat to cement fineness. It was observed that the 28 day mortar strengths represented a good predictor of the relative efficiencies of the cement.Key words: cement, concrete, compressi

Abstract:
The continuous tightening of emission limits for the production of harmful substances into the air and the rising price of emission allowances gradually force construction material producers to limit the use of binders with a high content of Portland clinker. In the production of concrete, this is achieved by using admixtures, which make it possible to reduce Portland cement doses. However, the single European market uses a method that maximises the use of blened cements, making it easier for cement plants to meet emission limits while not reducing cement production.

Abstract:
This research aims to investigate the influence of cement type to carbonation. For this purpose mixtures of four different cement mortars and eight different concretes that have been prepared with four different cements were left exposed for one year in open air in northern Greece. Results indicate that the type of cement influences the carbonation rate. Concrete mixtures produced according to the definitions of EN 206 standard perform lower service life against carbonation induced corrosion if the choice of the cement type is not carefully examined.

The binding properties of chloride ion of sulphoaluminate cement and portland cement were studied in different age,different water-cement ratio and different chloride ion content. The results show that binding rate tends to increase as the age and water-cement ratio increase for above two type cements. But the trend is opposite with the increase of total amount of incorporation chloride ion(TAIC), and the early strength of sulphoaluminate cement decreases slightly.

Abstract In vitro chemical stability and bioactivity of three different cement type bone substitutes were determined by incubating cement samples in the simulated body fluid (SBF) for 7 and 28 days. Morphology of sample surfaces has been studied using scanning electron microscopy (SEM) combined with an energy dispersive X-ray spectroscopy (EDS) and by atomic force microscopy (AFM). The diffuse reflectance Fourier-transform infrared spectroscopy (DRIFTS) was applied as a supplementary method. The development of bone-like apatite layers on the surface depended on their initial phase composition.

Problems due to the thaumasite form of sulfate attack (TSA), which has a significant influence on the strength and durability of buried concrete, have been extensively reported in the UK and worldwide. Thaumasite forms as a result of the presence of high levels of sulfate in pore waters in the ground surrounding concrete, particularly where sulfate is formed by the oxidation of pyrite and the ground temperature is less than about 12°C. In spite of this association with pyrite-bearing ground, an extensive literature search revealed that most previous research, including studies on which current

Abstract:
Concrete innovation in terms of changing some of its properties to improve quality and workability cannot be separated from the use of chemical additives, one of the admixtures that was used in this research was a type of superplasticizer with the brand Naptha Belide E121 Series. In this research the author wanted to examine the setting time admixture of Naptha Belide E121 Series in the application of 24-hour fast-track concrete K-500, the use of admixture doses in this research was 0%, 0.4%, 0.6% 0.8%, 1.0%, 1.2%, 1.4%, 1.6%, 1.8%, 2.0%, 2.2% of the weight of cement, while the cement used was

Abstract A series of 91 concrete G109 type specimens was exposed to cyclic wet-dry ponding with a 15 w/o NaCl solution for approximately four years.

Abstract Severe localized corrosion of a 316 stainless steel autoclave occurred during investigating Type H Portland cement stability in 0.16 M CaCl2 + 0.02 M MgCl2 + 0.82 M NaCl brine in contact with supercritical CO2 containing 4% O2. The system operated at 85°C and pressure of 29 MPa. However, no corrosion was observed in the same type of autoclave being exposed to the same environment, containing Type H Portland cement cylindrical samples, also operating at pressure of 29 MPa but at 50°C. The operation time for the 85°C autoclave was 53 days (1272 hours) while that for the 50°C autoclave w

Abstract The pH of the concrete pore solution is expected to be somewhat lower in concretes using pozzolanic additions than in concrete using unblended cements. Variations in pH pore solution may hold the key to explaining conflicting reports on the performance of galvanized rebar. To examine that factor, plain and galvanized rebars have been tested for over two years in concrete specimens made with cement type II, with various contents of fly ash and silica fume.

Abstract:
Rigid pavement is a type of pavement that uses cement as the main binding material and has a high level of stiffness. The prolonged use of cement has increasingly negative impacts on the environment. Using geopolymer as a substitute for cement can be an eco-friendly alternative solution. Geopolymer is an environmentally friendly material that can be developed as an alternative to cement concrete in the future. The purpose of this study is to determine the compressive strength of geopolymer concrete using rice husk ash and shell as fine aggregates in rigid pavement. The research method used is

Early-age cracking in concrete decks significantly reduces the service life of bridges.

Large-scale (7 ft × 10 ft) experimental bridge prototypes with similar restraint conditions found in actual bridges were poured with different concrete mixtures to investigate mitigation techniques. Portland cement (control), expansive Type K cement, internally cured lightweight aggregate (LWA), shrinkage-reducing admixture (SRA), and gypsum mineral were investigated as mitigating ingredie

Abstract:
Type K cement offers a lower slump than conventional concrete, even at a higher water-to-cement ratio. Therefore, a suitable chemical admixture should be added to the Type K concrete mix design at a feasible dosage to achieve and retain target slump. In this project, a compatibility study was performed for Type K concrete with commercially available water-reducing and air-entraining admixtures. Slump and air content losses were measured over a period of 60 minutes after mixing and a particular mid-range water-reducing admixture was found to retain slump effectively.

The deep mixing method is an in-situ ground improvement technique in which cementitious binder is mixed with soil using equipment that penetrates at least several meters into the ground. The mixing equipment can be vertical-axis rotating augers with mixing blades, horizontal-axis rotating wheels or drums with teeth, or chain-saw type equipment in which a chain with teeth moves around a post that is inserted into the ground. The product of deep mixing is referred to as "cement-treated soil" in this report to distinguish it from "soil-cement", which is a term that has long been used to refer to

Concrete laboratory mixtures containing C-S-H seeds X1 and X2 exhibited increased early-age strength and reduced permeability. Ba

Moreover, INDOT prefers using light weight deflectometer (LWD) for chemically modified subgrade construction acceptance, so this st
