水泥漿稠度測定儀
一、概述：水泥是采用硅酸鹽水泥或普通水泥，采用礦渣水泥時，應(yīng)加強檢查，以防止材性不穩(wěn)定。水泥的標號不宜低于425號。
水泥漿稠度宜控制在14-18S之間，稠度的測定采用1725ml漏斗試驗，水泥漿稠度測定儀生產(chǎn)廠家規(guī)格質(zhì)優(yōu)水泥漿從漏斗流出的時間（S），即為水泥漿的稠度。水泥漿面位置可用灌入1725ml水的方法找出。用點測規(guī)標記。
二、水泥砂漿參數(shù)
灰砂比        砂的種類       水灰比    水泥砂漿容重kg/m2    極限切應(yīng)力pa       粘度 pa.s

                         粗粒河砂      0.60             2180                               42.5                  0.60
                           河砂            0.52             2200                                42.8                 0.63
     1:2                 海砂            0.55              2160                               40.0                 0.50
                       粗粒河砂       0.78               2100                               41.5                 0.52
                        中料河砂       0.79              2230                               41.5                 0.48
     1:2.5           海砂                0.78           2200                                39.5                 0.54
                         粗粒河砂       0.81            2150                                44.5                 0.475
                         中粒河砂       0.79            2170                                 50.5                   0.48
      1:3                海砂              0.79           2120                                 43.0                  0.52
                       細粒河砂          0.91           2080                                 46.0                  0.46
                          粗粒河砂       0.88           2030                                40.6                    0.47
                          中粒河砂       0.83           2000                                44.0                     0.52
       1:1                河砂             1.03            2050                               39.0                    0.59
三、設(shè)備流動錐：出料管應(yīng)用不銹鋼制作，錐體可用鑄鋁或其他非腐蝕性材料制作。
注：只要能獲得水泥（砂）漿漿面的精確值，可以使用其他的指示裝置。接受容器：最小容量為2000ml環(huán)架或其他裝置：保持接受容器上方流動錐位置垂直和穩(wěn)定的裝置。水平尺：木工使用的或類似的水平尺秒表：最小讀數(shù)應(yīng)不大于0.1s。試驗設(shè)備校準：流動錐應(yīng)以無振動的方式安裝牢固。
