                                                           QUARTZ FLOUR                  FOR   PRODUCTION    HEAT RESISTANT     TAMBO     CEMENT   Cementing is one of the most complex and most critical operations in the technological cycle of well construction.   Geological conditions and features   sections of oil and gas fields are very diverse and complex.   Groutstone, ensuring the tightness of the wells for the first time hardening, after prolonged exposure, for example   high temperatures and reservoir pressures,   may lose its insulating properties. Therefore an urgent problem   is the creation of heat-resistant cement cements,    providing preservation of physical and mechanical properties of cement   stone in difficult geological conditions, including in the presence of high temperatures. Our company produces and offers silica flour (ground quartz) with a high content of silicon oxide   for    use as an active mineral additive in the manufacture of heat-resistant grouting cements.   This flour is produced by grinding vein chemically pure quartz. The degree of grinding of our quartz flour is similar to the fineness of grinding   cement Portland cement for elevated and moderate temperatures (passage through a sieve with a mesh No. 008 - at least 90%) Adding   quartz flour    effectively slows down the time of cement setting, provides uniformity and stability (non-separability) of the mortar, increases the strength of cement stone at high temperatures.           The use of heat-resistant cements allows for grouting in deep wells.   with elevated bottomhole temperatures (from 101 C to 150 C), as well as in the range of moderate temperatures (75 C or less),   providing high-quality fastening of casing strings throughout the placement interval   solution.   Granulometric composition of quartz flour: Sieve mesh size, mm 0.1 0.08 0.06 0.04 0.02 -0.02 Sieve residue,% 1,0 2.84 3.89 8.55 24.55 59.17   The content of SiO 2 - not less than 98% Humidity - not more than 0.7% The specific surface is 300-350 m2 / kg.     Products are delivered by railway wagons, railway 3, 5, 20-ton   containers, by road, in 1-ton MKR-1 soft containers, in bags of 25-50 kg.             Also at our dry mortar factory   production of grouting compositions according to recipes is possible   the customer. At the manufacturing stage   additional reagents or special additives (expanding, reinforcing, clogging, etc.) can be added to the cement, providing a ready-made dry mixture for specific hydrogeological conditions.

Repair mixture for concrete ICBM 500 Appointment : Dry construction mix MBR 500 is intended for the preparation of building fine-grained concrete (mortar) used for repairing concrete structures, monoling joints, technological holes, sealing cracks in concrete, brick walls, ceilings, etc. Composition :             Dry construction mix MBR 500   is a polymer-mineral fine-grained mixture obtained by intensive mixing of fractionated sand, Portland cement and a complex of modifying additives. Concrete preparation : For the preparation of dry building mix MBR 500   pour into clean fresh water, constantly mixing until a homogeneous mass is obtained using an electric drill with a mixer nozzle or a low-speed forced-action mixer. The amount of water required for the preparation of concrete is determined from the ratio of 0.18-0.19 l per 1 kg of dry construction mixture. Excess water contributes to the formation of cracks. Ready concrete must be used within 15 minutes. Preparation of the working surface (base) : The working surface (base) must be strong, durable, free of dust, dirt, oils, fats, wax, bitumen, paint residues, cement milk, efflorescence. Cracks are broken, old fragile concrete is removed, the released reinforcement is cleaned of rust. The prepared surface is cleaned of dust with compressed air, washed with water or treated with a sandblasting machine. It is necessary to treat with a polymer-mineral primer weak and highly absorbent substrates. Metal parts must be treated with an anti-corrosion solution. Concrete Application : Before applying concrete, the prepared surface is abundantly moistened. The water is allowed to soak and then manually apply concrete with a spatula. It is necessary to reinforce the applied repair layer with large areas of the surface to be repaired, repair of places subject to large bending loads, and a concrete layer thickness of more than 50 mm. Concrete laying is carried out without interruption until complete completion, or by grips. Before applying subsequent layers, it is necessary to moisten the previous layer, i.e. observe the processing method - “wet on wet”. The temperature of the working surface should be at least + 5ºС and not more than 30ºС. At negative temperatures up to -10ºС, the repair mixture MBR500M is used. To prepare the solution, it is necessary to use water at a temperature of at least 15 ° C. Stir the solution until the antifreeze additive is completely dissolved for at least 5 minutes from the moment of adding water. The consumption of dry mix depends on the type of repair. To repair a damaged horizontal surface with a repair layer thickness of 50 mm, 95-110 kg of mixture per 1 sq.m. To close a hole in a concrete wall with a diameter of 30-35 mm and a depth of 10 cm, 150-200 g of mixture is required, to close a crack with a width of 20 mm and a length of 1 m at a depth of 20 mm, 700-750 g of mixture are required.
