Early strength bearing mortar is an industry-leading product. It uses reasonably graded high-strength aggregate as aggregate, high-strength cement as binding agent, and high molecular polymer It is a toughening agent, supplemented by high fluidity, micro-expansion, anti-segregation, anti-cracking and other admixtures and admixtures, and is a professionally produced dry mix with precise proportions.
Scope of application:
Bearing mortar is a high-quality cement-based composite material used for the installation of highway and railway bridge bearings. Due to the use of a variety of high-performance additives, the finished surface is particularly smooth and flat. It overcomes the shortcomings of traditional mortar such as unevenness, cracking, and peeling, and has the characteristics of self-leveling, high early strength, high strength, no shrinkage, high wear resistance, and convenient construction.
Testing and certification:
Its performance indicators comply with national and railway industry standard technical requirements such as "Details for the Implementation of High-Performance Concrete for Beijing-Shanghai High-Speed Railway" and "Interim Technical Conditions for Pot-type Rubber Bearings for Passenger Dedicated Line Bridges" .
At present, various types of products such as prefabricated beams, cast-in-place beams, and extra-large bridges (types) have been formed, and construction techniques and construction auxiliary equipment under the conditions of -℃~-℃ in winter have been formed. Suitable for users to carry out construction under all-weather conditions.
Product features:
, has excellent fluidity, self-flowing leveling, no need for vibrating, troweling, construction speed is fast and convenient.
, has very high hourly strength, high late strength, and does not shrink. According to different construction temperatures, compressive strength and high flexural strength can be obtained in hours.
It has micro-expansion properties and excellent anti-cracking properties.
, adaptable to a wide temperature range, and can be constructed under -℃~℃ conditions without any auxiliary insulation or cooling measures. Under high or low temperature conditions, it can simultaneously ensure the needs of strength development and construction fluidity.
, Comply with the requirements of the "Temporary Technical Conditions for Concrete Precast Beams for Passenger Dedicated Lines" and "Temporary Technical Conditions for Pot-type Rubber Bearings for Bridges on Passenger Dedicated Lines"
, suitable for emergency repairs, track filling, and bearing grouting, especially Suitable for high-speed railway bridge supports or track filling, etc. It can also be used for local leveling of concrete beams or repair of concrete piers.
Working principle:
Complies with the requirements of the "Temporary Technical Conditions for Concrete Precast Beams for Passenger Dedicated Lines" and the "Temporary Technical Conditions for Basin Rubber Bearings for Bridges on Passenger Dedicated Lines"
Construction methods:
, Chisel the surface of the supporting pads at the bearing installation site, remove debris left in the anchor bolt holes, and then saturate the surface of the supporting pads with water, but no open water is allowed during construction.
. Install the support in place, use small steel wedges to wedge around the support, and adjust the support to the design elevation. There should be a gap between the bottom surface of the support and the supporting pad.
After carefully checking the center position and elevation of the support, install the grouting formwork. Reliable measures should be taken on the formwork and the top surface of the padding stone to prevent grout leakage during gravity grouting. The bearing grouting material is poured using gravity grouting. The required slurry volume should be initially measured before grouting. The actual amount of grouting grout should not have too large an error with the calculated value to prevent lack of grout in the middle.
Prepared with a water-to-material ratio of .3 (weight ratio). Water should be added into the mixing barrel first, and then the weighed grouting material should be gradually added. Stir with an electric mixing gun while adding the material, until all the powder is added, and then continue stirring for another minute to make the slurry uniform. The mixed slurry should be poured within minutes.
After the grouting material reaches the specified strength, remove the formwork and steel wedges, check whether there is grout leakage, fill the grout leakage and the gap after the steel wedges are pulled out, tighten the anchor bolts, and then install the beams Body support bottom plate and support sealing enclosure.
Packaging and storage:
,/bag, packaging specifications can be customized according to customer requirements.
. It should be stored in a cool, dry and ventilated place indoors.
