Thermodynamic Modeling of the Effects of Wollastonite-Silica Fume Combination in the Cement Hydration and Sulfate Attack
Sulfate attack is a series of physico-chemical reactions between hardened cement paste and sulfate ions. Sulfate ion penetration into the hydrated cement results in the formation of voluminous and deleterious phases such as gypsum and ettringite which are believed to cause deterioration and expansion of concrete. Concrete deterioration due to sulfate attack depends on many parameters, however, ...
متن کاملSimulation of Expansion in Cement Based Materials Subjected to External Sulfate Attack
Sulfate attack in concrete structures is considered to be among the major durability concerns in civil infrastructure systems. Proper modeling techniques can help us understand the influence of aggressive environments on the concrete performance more readily and accurately. Such an understanding improves the decision making process in every stage of construction and maintenance and will help in...
متن کاملPCTs consider alternative to homeopathic hospitals.
One of England's four homeopathic hospitals is at risk of closure because of primary care trusts' reluctance to refer patients outside the NHS mainstream. Other homeopathic hospitals are also facing severe financial problems Kent PCT, which runs Tunbridge Wells Homeopathic Hospital and also refers the majority of patients, is consulting on whether to vet all referrals made by GPs to the hospita...
متن کاملDamage Evolution of Concrete Exposed to Sulfate Attack Under Drying- Wetting Cycles
The damage evolution of concrete subjected to drying-wetting cycles in different concentration of sodium sulfate solution was investigated based on micro and macro-observations. Through the experiment, weight loss, compressive strength loss and the damage layer thickness of concrete were measured after different drying-wetting cycles. The mechanical properties degradation in the damage layer of...
متن کاملConsider the Strip-Tillage Alternative
seed germination, is a new alternative to no-till in areas where poorly drained soils are dominant. Where soil moisture conditions are suitable, strip-tillage creates narrow-width tilled strips, traditionally in the fall, to increase early spring soil evaporation and soil temperature in the top 2 inches. This is particularly effective in poorly drained wet soils, where slightly raised soil stri...
