German Chongqing New Asia Polymer rapid structural repair material manufacturers 13,311,126,842 German Chongqing New Asia Polymer rapid structural repair material manufacturers 13,311,126,842 German Chongqing New Asia Polymer rapid structural repair material manufacturers 13,311,126,842 German Chongqing New Asia Polymer Rapid structural repair materials manufacturers 13,311,126,842 polymer rapid structural repair materials - Technical Guide I. Introduction polymer material rapid structural repair materials, is a cement-based binders, high-strength materials (quartz sand) as the primary aggregate and auxiliary In polymer powder, superplasticizer, the early strength, bulking agents, anti-segregation and other substances from the preparation of ultra strength concrete structures repair material. This product has gravity and good, fast hard, early strength, high strength, non-shrink, micro-expansion; non-toxic, harmless, non-aging, water quality and the surrounding environment pollution, since tightness is good, rust and other characteristics. Polymer rapid structural repair materials, is Henan Transportation Research Institute of Science and Technology Co., Ltd., Henan Province, traffic engineering reinforcement limited liability company, Beijing Sino-German New Asia Construction Co., for the characteristics of concrete structures damaged, the joint development of high-performance Ultra-early-strength concrete structure repair material. Fourth, the technical requirements specified in Table 1 Polymer rapid structural repair materials Technical Requirements Specification requirements for bridge expansion joints and concrete technical quick fixes municipal road inspection wells runway extensions of the slump and slump (mm) slump initial value ≥270 - - ≥220 initial fluidity ≥320mm extended slump of the initial value ≥650 --- ≥500 30min fluidity ≥240mm 30min slump retention value ≥240 --- ≥200 30min extended slump retention value of ≥550 - - ≥400 Compressive Strength (Mpa) 3h ≥30 ≥30 ≥30 ≥30 1d ≥40 ≥40 ≥40 ≥40 28d ≥60 ≥60 ≥60 ≥60 flexural strength (Mpa) 3h ≥4 ≥4 ≥4 ≥4 1d ≥5 ≥5 ≥5 ≥5 28d ≥8 ≥8 ≥8 ≥8 bonding strength Mpa 3h ≥1.5 ≥1.5 ≥1.5 ≥1.5 free expansion% 1d ≥0.02 ≥0.02 ≥0.02 ≥0.02: 1. Table of performance indicators should be according to the maximum amount of water the product required inspection. Fifth, use 1 Scope A. bridge expansion joint special cement concrete pavement broken board quick fixes. B. concrete structures severely damaged parts of the quick fix. Rapid repair of concrete structures quick fix structural member A. damaged concrete surfaces, beams, plates and other parts. A. Well dedicated municipal road inspection manholes rapid repair of municipal roads 2, the construction process (1) Process ① ② concrete structure bridge expansion joint special quick fix municipal road inspection wells private (2) the construction process ① bridge expansion joints private (airport runway Dedicated) A. Cleanup: For cement concrete pavement broken board or severely damaged parts of the concrete structure, with picks the broken plate is broken into small pieces after clearing the plate around the base to completely remove loose material and air compressor The base surface and blowing dust tank. B. base surface infiltration: in 2 to 3 hours before pouring the base surface and removing water to fully wet out of water; winter construction, before pouring the base should not exceed 65 ℃ face with warm water to fully wet and removed out of water. C. interface treatment: the base surface evenly brushing a layer of polymer based interface agent. D. formwork: Located in the middle of the road to be repaired in the cement concrete pavement, can be used as a template around the board edge; to be repaired is located in cement concrete pavement road edge, which can be used around the three sides of the plate edge as a template , the edge should die or steel standing support and to take measures to leak plasma. For severely damaged parts of the concrete structure, should support legislation setting a template and take measures to leak plasma. E. mixed system: according to the number of on-site pouring and pouring speed, the repair material artificially forced into the mortar mixing machine, dry mix 10s, after the product prescribed by weighing the amount of water, mixing with water twice: the first Canadian 2/3 water, mixing 30s; second plus 1/3 water, mixing 150s. After mixing, the patch material should stand for 2 ~ 3min, to be carried out after pouring the bubble disappears. Winter construction, should not exceed 65 ℃ of warm water mixing, pouring temperature should be above 10 ℃. F. Placement: pouring vessel with a slow, uniform pouring dense, should be pouring avoid hollowing phenomenon. After pouring over, smoothing the top surface of the patch material. Every system of repair materials mix, mix from the beginning to the pouring end system, time shall not exceed 30min. Pouring out or does not meet the liquidity requirements of the repair materials, can not continue to use. G. Health: plastic strip covering the top surface of the patch material, then completely covered with straw on the plastic strip to keep moist. At room temperature, after 3 ~ 4h to end health, or in accordance with structural strength requirements and provisions specimen strength test results to decide whether to end health. Winter insulation measures should be adopted, and health appropriate to extend the period.
