This study analysed the results of the joint research into the building materials of the historic masonry of the retaining wall of the Gediminas Castle Hill dating back to the end of the 13th and beginning of the 14th centuries.

This paper studies how pozzolan properties including particle size, specific surface, chemical and mineral composition, amorphousness and water demand, affect their reactivity as well as the strength of lime—pozzolan pastes. Reactivity was evaluated with chemical, mechanical and mineralogical methods. It was evidenced that each pozzolan has a particular water demand for a given workability that increased with its specific surface; and that the replacement of lime by pozzolan lowers the water demand of the paste except for Metastar, on account of its greater fineness and specific surface.

Lime (material)

Clay soils are known for their water sensitivity, which causes irreparable damage to any structure built on this type of soil. In order to avoid such problem, it is necessary to use various improvement and stabilization methods such as treatment with lime. This process has been used successfully in the field for decades. The addition of lime generates various physicochemical reactions within the soil such as cation exchange and pozzolanic reactions which are largely responsible for the improvement of the soil in question.

This paper presents a study concerning the variation of physicochemical properties of clayey soil with the addition of quicklime at different percentages.

Experiments were performed on two clayey soils CL type in order to investigate the influence of quicklime on Atterberg limits and pH. These tests were carried out in an attempt to study and follow the development and progression of various reactions occurred within the soil with various lime percentages. The results show that the addition of quicklime causes a significant improvement in soil properties by reducing plasticity and thereby improves the soil workability.

It can also be found that the addition of lime increase pH of soil, which allow activating pozzolanic reactions who tend to stabilize the soil in question by formation of cementitious compounds.

Finally, the pH can be considered as a relevant parameter who allows a better understanding of the reactions that occur in the soil matrix.

It is seemed that the properties of slaked lime obtained by slaking of quick lime is different more or less if the characteristics of the quick lime as a row material, the methods and also the conditions of slaking are suitable. Although it's many reporting of there matter, we studied on the properties of slaked lime, slaking the quick lime obtained by the same conditions as III and IV reports express. This tendency is remarkable in the care of calcination the low temperature. It finds no effect by the calcinating temperature. Excepting the slaked lime obtained by natural slaking, they are similar as the result, even in any method and are little effects by the calcinating temperaturs and the method of slaking.

The patented methods of making manganese arsenates for insecticidal use consist in treating a manganese compound, such as pyrolusite, with white arsenic As 2 O 3 in the presence of nitric acid as a catalyst. The manganous arsenate formed is partly converted to the trimanganoarsenate by treatment with manganese carbonate to lower the water soluble arsenic content. The brown color of the insecticide is produced by treating the mixed arsenates with lime, which decomposes some of the arsenates with the formation of calcium arsenate and hydrated oxides of manganese.

Search Titles Subjects Organizations Collage. Limestone is a sedimentary rock composed mainly of calcium and magnesium carbonate. Limestones are contaminated to a greater or lesser extent by the deposition of sand" or clay which are the source of the impurities found in them. Usually there is a difference in quality in a deposit from one layer to the next. The purest carbonates and the most suitable from the production point of view tend to be the thick bedded type.

 Если только Стратмор не придумал что-то особенное и не обошел мои фильтры. Повисла тягостная тишина. Когда Мидж заговорила, ее голос был мрачным: - Стратмор мог обойти фильтры. Джабба снова вздохнул.

После минутного упорства ему придется уступить. Но если я вызову агентов безопасности, весь мой план рухнет, - подумал. Хейл сдавил горло Сьюзан немного сильнее, и она вскрикнула от боли. - Ну что, вы решили. Я ее убиваю.

Однако тот не подавал никаких признаков жизни. Сьюзан перевела взгляд на помост перед кабинетом Стратмора и ведущую к нему лестницу. - Коммандер. Молчание.
