Cement and aggregate mixture and method for making same

A resilient material such as rubber is pulverized into particles. The particles are then coated with dry cement. In one embodiment of the invention the coating may be accomplished by heating the particles until their outer surfaces become viscid and the mixing the particles with cement so that when the cement contacts the viscid outer surfaces, it will adhere thereto, enveloping the particles with a layer of cement. In another embodiment, the cement may be heated and then brought into contact with the particles. The outer surfaces of the particles will become adhesive and the cement will adhere thereto. In a further embodiment, the particles may be coated with a plastic film. The plastic coated particles are then coated with cement as described. Alternatively the plastic coated particles may be mixed with the cement before the plastic has set. The cement will adhere to the still unset plastic coating. In each of the embodiments, the cement will be permanently bonded to the particles. The cement coated particles are then combined with additional cement to form a cement and aggregate mixture at a predetermined ratio of particles to cement. When water is added to the cement and aggregate mixture in an amount sufficient to cause the cement to set or gel irreversibly, a light weight, resilient concrete is formed. Since the cement is bonded either directly to the particles or to the plastic coating surrounding the particles, it will not readily separate therefrom and the particles will become an integral part of the concrete which results in the concrete having physical properties different from ordinary concrete. Where the particles are coated with plastic to aid in the adhesion of the cement to the particles, the plastic film further acts as a barrier to prevent fluid flowing over the concrete from contacting the particles and picking up impurities which would stain the concrete.

여기에는 인덕터 형성 방법이 개시된다. 이 인덕터는 기판위에 인덕터 패턴을 형성하고 인덕터 패턴의 표면적을 증가시키기 위하여 인덕터 패턴위에 요철 구조를 갖는 도전 패턴을 더 형성한다. 이를 위하여 인덕터 패턴위에 절연막을 형성하고 인덕터 패턴이 드러나도록 절연막을 제거하여 그루브를 형성한 후 그루브와 절연막 상에 콘포멀하게 도전 패턴을 형성한다. 따라서 인덕터 패턴의 표면적 증가 뿐 아니라 인덕터의 두께도 증가하여 하이 퀄리티 팩터의 인덕터를 얻을 수 있다. Disclosed is a method of forming an inductor. This inductor further forms a conductive pattern having an uneven structure on the inductor pattern to form an inductor pattern on the substrate and increase the surface area of the inductor pattern. To this end, an insulating film is formed on the inductor pattern, the insulating film is removed to form a groove so that the inductor pattern is exposed, and then a conductive pattern is formed conformally on the groove and the insulating film. As a result, not only the surface area of the inductor pattern is increased but also the thickness of the inductor is increased, thereby obtaining a high quality factor inductor.

Surface-treated additive to concrete-portland cement mix

FIELD: chemical industry. SUBSTANCE: additive is surface-treated additive where surfaces of additive are treated with agent which produces hydrophobic effect on additive. This effect makes additive more hydrophobic during period of time which follows inclusion of additive into composition, and water present in composition is absorber by additive to smaller extent, and hence becomes less suitable for preparation of composition suitable for serviceability thereof, and additive restores its natural properties after composition has been placed so that additive participates during solidification of composition. Also described are method of preparing additive and method additive-containing binding composition. EFFECT: additive to binder and concrete which increases strength and improves wetting time without any substantial increase in the desired water- cement ratio. 77 cl, 1 ex 658 491сС ПЫ с» (19) РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (11) КО 2 167 839 5 МК’ С 04 В 20/10, 7/00, 24/10 (13) С2 (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 99114779/03, 09.12.1997 (24) Дата начала действия патента: 09.12.1997 (30) Приоритет: 10.12.1996 ЦЗ 08/763,088 (43) Дата публикации заявки: 10.05.2001 (46) Дата публикации: 27.05.2001 (56) Ссылки: ОЕ 4325797 АЛ, 02.02.1995. $Ц 120756 А, 06.09.1961. $Ц 239836 А, 11.08.1969. $Ч 483311 А, 12.12.1915. $Ц 1010038 А, 07.04.1983. $Ц 1803396 А\, 23.03.1993.

Early high-strength portland cement and method of manufacture

A cement with rapid strength gain having normal setting and volume change characteristics and its method of manufacture are disclosed. The cement has substantially all particles over 20 microns removed which advantageously results in higher early strength than normal portland cements. This is important in the prestress and precast concrete industry, and early high-strength cement is desirable for other uses such as patching or resurfacing highways and airport runways or in operations where early form removal is desired. The use of chlorides or other accelerators is unnecessary to obtain early high strengths; although, these and plasticizers can be used if desired.

Это достигается тем, что заполнитель бетона смачивают в пластичном цементном тесте, при этом цементное тесто поддерживают в тиксотропном состоянии, например, вибрированием. При необходимости заполнитель в процессе транспортирования смачивают в потоке цементного теста.
