濟(jì)南水穩(wěn)料施工時(shí)注意事項(xiàng)

水穩(wěn)料主要由粒料和灰漿體積組成。由水泥、石灰、石膏等膠凝材料加水拌合而成的漿狀混合料，用于粉刷或灌縫。那么濟(jì)南水穩(wěn)料施工時(shí)注意事項(xiàng)是什么呢？

Water stabilized material is mainly composed of granular material and mortar volume. A slurry mixture made of cement, lime, gypsum and other cementitious materials mixed with water, which is used for painting or joint filling. So what are the precautions for the construction of water stabilized materials in Jinan?

攪拌設(shè)備的選擇

Selection of mixing equipment

攪拌設(shè)備的好壞直接影響到混合料的攪拌質(zhì)量，而攪拌設(shè)備質(zhì)量好壞的關(guān)鍵在于能否保證骨料、粉料、水等物料的混合比例精度。本標(biāo)段采用WBC300型穩(wěn)定土植物攪拌設(shè)備。設(shè)備采用電磁調(diào)速系統(tǒng)，能更好地保證各種物料的混合比，混合均勻，性能穩(wěn)定。

The quality of mixing equipment directly affects the mixing quality of mixture, and the key to the quality of mixing equipment is whether to ensure the mixing proportion accuracy of aggregate, powder, water and other materials. Wbc300 stabilized soil plant mixing equipment is used in this bid section. The equipment adopts electromagnetic speed regulation system, which can better ensure the mixing ratio of various materials, uniform mixing and stable performance.

嚴(yán)格控制水泥用量

Strictly control the amount of cement

水泥用量過少，水泥穩(wěn)定土的施工質(zhì)量得不到保證；用量太大不經(jīng)濟(jì)，而且會(huì)增加和擴(kuò)大基層裂縫，從而在瀝青面層造成相應(yīng)的反射裂縫。因此，必須嚴(yán)格控制水泥用量，做到經(jīng)濟(jì)合理，精益求精，確保工程質(zhì)量。

Too little cement is used, and the construction quality of cement stabilized soil can not be guaranteed; It is uneconomical to use too much, and it will increase and expand the cracks in the base course, resulting in corresponding reflection cracks in the asphalt surface course. Therefore, the cement consumption must be strictly controlled to achieve economic rationality, keep improving and ensure the project quality.

混合物的水分控制

Moisture control of mixture

在工廠拌合現(xiàn)場，后院的專職測試人員會(huì)在上午、中午和下午分別測量各種骨料的含水率，根據(jù)根據(jù)施工配合比設(shè)計(jì)的最佳含水率指標(biāo)，結(jié)合氣溫，當(dāng)天的濕度和運(yùn)輸距離。

At the factory mixing site, full-time testers in the backyard will measure the moisture content of various aggregates in the morning, noon and afternoon respectively. According to the best moisture content index designed according to the construction mix proportion, combined with the temperature, humidity and transportation distance of the day.

這種情況決定了混合混合物時(shí)要使用的水量。前院負(fù)責(zé)測試壓實(shí)度的專職測試人員在攤鋪成型混合料的過程中也及時(shí)測量混合料的含水量，并指導(dǎo)壓路機(jī)及時(shí)碾壓，所以盡量在最佳含水率條件下滾動(dòng)，盡量避免。

This determines the amount of water to be used when mixing the mixture. The full-time tester in charge of testing the compactness in the front yard also measures the water content of the mixture in time during the paving of the formed mixture and guides the roller to roll in time. Therefore, try to roll under the condition of the best water content and avoid it as much as possible.

因含水量過大而產(chǎn)生“彈性”和“波浪”現(xiàn)象，混合料可能達(dá)到密度和強(qiáng)度，增加混合料的干縮，使結(jié)構(gòu)層容易出現(xiàn)干縮裂縫；或由于含水量低，使混合料容易松散，不易卷成形狀，也影響混合料可能的密度和強(qiáng)度。因此，只有嚴(yán)格按照規(guī)范施工，加強(qiáng)各個(gè)施工環(huán)節(jié)的質(zhì)量控制，才能保證施工質(zhì)量。

The phenomenon of "elasticity" and "wave" due to excessive water content, the mixture may reach density and strength, increase the dry shrinkage of the mixture, and make the structural layer prone to dry shrinkage cracks; Or due to low water content, the mixture is easy to loose and not easy to roll into shape, which also affects the possible density and strength of the mixture. Therefore, the construction quality can be guaranteed only if the construction is carried out in strict accordance with the specifications and the quality control of each construction link is strengthened.

減少混合物的離析

Reduce segregation of mixture

混合物的運(yùn)輸應(yīng)避免車輛碰撞。氣溫高、運(yùn)輸距離長時(shí)，應(yīng)蓋好氈布，以防水分過度流失。攤鋪和碾壓時(shí)，攤鋪系數(shù)在1.3∽1.5之間，濟(jì)南水穩(wěn)料施工中必須貫徹“低不刮”，所有建設(shè)項(xiàng)目應(yīng)在水泥終凝時(shí)間前完成。滾壓后立即進(jìn)行密實(shí)度測試，如果測試結(jié)果不符合標(biāo)準(zhǔn)，重新滾壓。

The transportation of the mixture shall avoid vehicle collision. When the temperature is high and the transportation distance is long, the felt cloth shall be covered to prevent excessive loss of water. During paving and rolling, the paving coefficient shall be between 1.3 and 1.5. The "low without scraping" must be implemented in the construction of water stabilized materials in Jinan, and all construction projects shall be completed before the final setting time of cement. The compactness test shall be carried out immediately after rolling. If the test result does not meet the standard, it shall be rolled again.
