Fracture Mechanics of Asr in Concretes with Waste Glass Particles of Different Sizes
Using waste glass as an aggregate in concrete can cause severe damage because of the alkalisilica reaction (ASR) between the alkali in the cement paste and the silica in the glass. Recent accelerated 2week tests, conducted according to ASTM C 1260, revealed that the damage to concrete caused by expansion of the ASR gel, which is manifested by strength reduction, depends in these tests strongly ...
متن کاملEffect of Alkali Silica Reaction (ASR) in Geopolymer Concrete Final
Alkali silica reaction (ASR) occurs due to chemical reaction between hydroxyl ions in the pore water within the concrete matrix and certain forms of silica. This reaction could lead to strength loss, cracking, volume expansion and potentially failure of the structure. This manuscript reports findings of an experimental investigation of the inter-particle bonding between the reactive aggregates ...
متن کاملInhibitory Effect of Waste Glass Powder on ASR Expansion Induced by Waste Glass Aggregate
Detailed research is carried out to ascertain the inhibitory effect of waste glass powder (WGP) on alkali-silica reaction (ASR) expansion induced by waste glass aggregate in this paper. The alkali reactivity of waste glass aggregate is examined by two methods in accordance with the China Test Code SL352-2006. The potential of WGP to control the ASR expansion is determined in terms of mean diame...
متن کاملthe effect of explicit versus implicit error correction on writing of iranian intermediate efl learners
در این پایان نامه دو روش اصلاح اشتباهات نوشتاری زبان آموزان بزرگسال ایرانی در سطح متوسط مورد بررسی قرار می گیرد. در روش اول (explicit) اشتباهات بطور مستقیم و در روش دوم (implicit) اشتباهات بصورت غیر مستقیم اصلاح می شود. برای انجام این تحقیق از دو گروه 15 نفری استفاده شده است. به زبان آموزان در هر جلسه یک موضوع انشا داده شده است. این کار در 15 هفته (15 جلسه) تکرار شده است. مقایسه نتایج این آزمون...
Effect of Volume Expansion
The clinical and hemodynamic effects of rapid atrial pacing were studied in 13 patients with coronary artery disease and four normal subjects before and following acute expansion of blood volume with low molecular weight dextran. Five patients developed angina during the initial pacing period. In two of these five patients angina recurred with infusion alone, and all five of them experienced pa...
