影響混凝土攪拌機產品質量的因素有哪些?
影響混凝土攪拌機的因素有很多,今天中科攪拌車小編就帶大家一起來了解下主要的幾點影響因素,來看看吧。
There are many factors that affect the concrete mixer. Today, we will take you to understand the main factors. Let's have a look.
一、混凝土的配合比要正確;
1、 The mix proportion of concrete should be correct;
二、攪拌站中的稱量系統(tǒng)要精確;
2、 The weighing system in the mixing station should be accurate;
三、原材料質量的選擇準確。以下是對混凝土原材料選擇控制要求:要從源頭上把好水泥、粗細骨料、外加劑、礦物外摻料品質關,原材料品質要求在供貨合同中明確。
3、 The selection of raw material quality is accurate. The following are the control requirements for the selection of concrete raw materials: the quality of cement, coarse and fine aggregates, admixtures and mineral admixtures shall be well controlled from the source, and the quality requirements of raw materials shall be specified in the supply contract.
1、水泥:水泥進場必須按規(guī)定進行抽樣檢驗,每批進場的水泥均要求及時進行標準稠度與溫度測試,對質量存有懷疑的嚴禁入倉,并繼續(xù)進行其他指標(如安定性)測試,經檢驗不合格的水泥嚴禁進場。嚴禁未經均化(消解)的熱水泥直接使用于工程,對于已使用的水泥要進行追溯,并填制"水泥使用追溯表"。
1. Cement: sampling inspection must be carried out for cement entering the site according to the regulations. Standard consistency and temperature test shall be conducted for each batch of cement entering the site in time. If there is any doubt about the quality, it is forbidden to enter the warehouse, and other indicators (such as stability) test shall be continued. The cement that fails to pass the inspection is not allowed to enter the site. Hot cement without homogenization (digestion) is strictly prohibited to be directly used in the project. The used cement shall be traced and the "cement use traceability table" shall be filled in.
2、骨料:粗細骨料進場必須按規(guī)定進行抽樣檢驗,檢驗合格方可使用。粗骨料應選用級配合理、粒形良好、質地均勻堅固的碎石或碎卵石,粗骨料各種指標應滿足相關標準規(guī)范的要求;控制泥含量和泥塊含量,及時進行檢測,經檢驗不合格的嚴禁進場卸車。
2. Aggregate: coarse and fine aggregate must be sampled and inspected according to the regulations, and can be used only after passing the inspection. The coarse aggregate shall be gravel or pebble with reasonable gradation, good grain shape and uniform and firm texture, and various indexes of coarse aggregate shall meet the requirements of relevant standards and specifications; the content of mud and clay block shall be controlled, and timely detection shall be carried out. The unqualified ones shall not enter the site for unloading.
3、外加劑:外加劑進場時應加強檢查、檢測,檢查外加劑的包裝上是否在明顯位置上注明以下內容:產品名稱、型號、凈含量或體積(包括含量或濃度)、生產廠名、生產日期及出廠編號;檢查包裝物所標明的內容是否與生產廠家提供的產品說明書、合格證相符;液體外加劑是否析出沉淀物,是否超過有效期。
3. Admixtures: when admixtures enter the site, inspection and testing shall be strengthened to check whether the following contents are clearly indicated on the package of admixtures: product name, model, net content or volume (including content or concentration), manufacturer name, production date and factory number; whether the contents marked on the package are consistent with the product instructions and certificates provided by the manufacturer; Whether the liquid admixture precipitates precipitates and whether it exceeds the validity period.
4、礦物外摻料:根據有關標準規(guī)范的要求進行檢測。試驗室應隨時掌握礦物外摻料的質量變化情況,礦物摻料進場時,必須進行需水量比、燒失量、細度檢測,經檢驗合格的產品方可入庫;并注意與前期試驗結果進行對比,以判定質量的波動情況,確保工程質量。在礦物外摻料的使用過程中,應盡量確保外摻料的相對穩(wěn)定性。應與物資部門進行溝通,確保對于同類別的外摻料,一個攪拌站應盡量使用同一廠家的商品。當無法滿足要求時,試驗部門應及時進行配合比調整,嚴禁礦物外摻料的混用。
4. Mineral admixture: according to the requirements of relevant standards and specifications for testing. The laboratory should master the quality changes of mineral admixtures at any time. When mineral admixtures enter the site, water demand ratio, loss on ignition and fineness test must be carried out, and the qualified products can be put into the warehouse; and the comparison with the previous test results should be paid attention to determine the quality fluctuation and ensure the engineering quality. In the process of using mineral admixture, the relative stability of mineral admixture should be ensured as far as possible. Communicate with the material department to ensure that for the same kind of admixture, one mixing plant should use the same manufacturer's products as far as possible. When the requirements can not be met, the test department should adjust the mix proportion in time, and it is forbidden to mix mineral admixture.
5、攪拌站材料員要及時關注庫存料的情況,并要有預見性及憂患意識,積極組織備料,避免出現停工待料,特別要關注散裝水泥的結存。對庫存的物資要掛牌標識,隨時保證現場材料的堆碼,嚴格按分倉進行原材料的存放。
5. The materialman of the mixing plant should pay attention to the stock situation in time, have the foresight and the sense of worry, actively organize the preparation of materials, avoid the occurrence of shutdown and waiting for materials, and pay special attention to the balance of bulk cement. The materials in stock shall be marked with tags to ensure the stacking of materials on site at any time, and the raw materials shall be stored strictly according to different warehouses.
