Flexural Strength Models for Normal Laterised and High Strength Laterised Concretes at Optimum Mix Proportions
نویسندگان
چکیده
This study develops mathematical models for obtaining optimum flexural strengths of normal laterised(NLC) and high strength laterised concretes (HSLC). The can be expressly used to evaluate the indirect tensile both types without going through traditional methods mix design. Optimum mixing ratios predicted are also supplied by models. three point load method was adopted testing strengths. Laterite, has been widely partially or wholly replace sand in concrete with resultant low production HSLC using superplasticiser achieved this study. Scheffe’s simplex theory based on (5, 2) lattice (for NLC) (6, HSLC) optimize proportions each respective concrete. Conplast SP 430 (a sulphonated naphthalene formaldehyde admixture) obtain Mathematical were developed proportioning all agreed their corresponding experimentally observed values. Using model, targeted could easily evaluated help written Q-BASIC computer programme.

Effect of high-concentrated bleaching agents on the bond strength at dentin/resin interface and flexural strength of dentin.
This study evaluated the effect of bleaching agents on bond strength at the dentin/resin interface and the flexural strength of dentin. Forty maxillary canines were selected for the study. In the shear strength test, 40 slabs of intracoronary dentin (5 x 5 mm) obtained from buccal surfaces of the crowns were included in acrylic resin. In the flexural strength test, 40 dentin bars (8 x 2 x 2 mm)...

BACKGROUND The radiopacity degree of posts is not enough for adequate visualization during radiographic analyses. Glass fiber post with stainless steel reinforcement has been fabricated in an attempt to overcome this limitation. AIM This study was designed to determine the influence of this metal reinforcement on the post mechanical properties. MATERIALS AND METHODS This study evaluated fle...
متن کاملInfluence of High Temperatures on Flexural Strength of Foamed Concrete Containing Fly Ash and Polypropylene Fiber
In this study, the elevated temperature flexural strengths of lightweight foamed concrete (LFC) containing fly ash (FA) and polypropylene fiber (PF) was investigated experimentally and statistically. The variables included were the temperature degrees (in a range of 20 to 600°C), LFC densities of 600, 800, 1000, 1200 and 1400 kg/m3 and additive content. Two mixes were made by replacing 15% and ...
