It mainly consists of special cementitious material, expansive materials, high aggregate and composed of multiple admixtures. Now on the test results in this paper.1 、流動度1, the fluidity　　流動度指標是灌漿施工有無成效的重要條件。根據國外設計，一般要求灌漿料的跳桌流動度大于 240mm，以保證灌漿料依靠自重或稍加插搗就能流進所要填充的全部空隙。按不同水料比測定的 CGM 灌漿料的流動度和強度 ( 見圖 1 與表 2) ，圖 1 表 2 顯示 灌漿料隨著用水量的增加流動度增大，而抗壓強度則降低。　　The fluidity indexes is without effective grouting construction is an important condition. According to the foreign design, general requirement grouting material jump table 240mm fluidity than to ensure grouting materials depend on passengers or slightly beaten can flow into inserted to fill all the gap. According to different water than determination CGM grouting material feeding fluidity and intensity (see chart 1 and table 2), figure 1 chart 2 grouting material with the increase of water flow degree increased, and the compressive strength is lower.表 2用水量對流動和強度的影響Table 2 water to flow and intensity of influence

　　根據試驗，在不同溫度條件下該材料流動性延續時間對流動度影響見表 3 。施工中應注意對攪拌好的灌漿料不宜久置。　　According to the experiments, under different temperature conditions the material for the duration liquidity fluidity influence to table 3. Construction attention should be paid to stir good grouting material shoulds not be long offsets.表 3時間延續對流動度的影響Table 3 time continuance of the fluidity of influence

13	35	260	250	200	175	140

2 、凝結時間2, setting time　　灌漿料的凝結時間直接影響到施工連續性和質量。BT-6022中膠凝材料的水化速度隨環境溫度不同而改變，凝結時間也隨之變化。所測定的不同溫度和流動度 CGM 的凝結時間 ( 表 4) ，可供不同條件下施工參考之用。　　Grouting material setting time directly affect the construction continuity and quality. In BT-6022 cementitious materials of hydration speed with different environmental temperature changes, setting time changed also. Determine different temperatures and fluidity CGM of setting time (table 4) for different conditions construction reference.表 4 BT-6022的凝結時間Table 4 BT-6022 of condensate time

270	10	5.8	8.3
210	10	5.6	8.0
270	35	2.8	4.9

3 、限制膨脹性3, restricted expansion　　在設備安裝中，用灌漿料澆筑的二次灌漿層上表面高度不能低于初始表面高度，而且要向上有一定膨脹變化，這種變形稱為豎向限制膨脹。地腳螺栓的錨固有一定的膨脹應力，使螺栓錨于應力場中，可大大地提高抗拉拔的能力。見圖 2 、表 5 表明BT-6022灌漿料在常溫下都有一定的豎向限制膨脹性，限制膨脹率在 0.010％～0.040％范圍內，并在灌漿后十天左右開始穩定。　　In equipment installation, use grouting material casting of secondary layer surface height grouting cannot under initial surface height, but also to have certain upward expansion change, this kind of vertical deformation called restricted expansion. The anchor bolt anchor has certain expansive stress, bolt anchor in stress field, it can greatly increase tensile pull ability. See chart 2 and table 5 grouting material that BT-6022 at room temperature are certain vertical limit the dilatability, limit inflation in 0.010%～0.040% range, and in approximately ten days after grouting began to stabilize.表 5 BT-6022在常溫膨脹率％Table 5 BT-6022 in room temperature inflation %

1d	2d	3d	7d	10d	14d	28d
0.008	0.010	0.012	0.026	0.030	0.032	0.036

4 、抗壓和抗折強度4, compressive strength and flexural strength　　按國內規范要求，一般設備安裝的二次灌漿采用的細石混凝土強度應比設備基礎混凝土高一級。當用無墊板方式安裝設備時，按國外設計要求，灌漿料的一天抗壓強度要達到 30MPa ， 28d 抗壓強度達到 60MPa ，甚至更高 ( 如鋼連鑄 ) 。為了滿足上述設計要求，在對BT-6022 原材料配比進行大量試驗研究后，測定的抗壓、抗折強度的范圍值見表 6 。　　According to the domestic requirements specification, general equipment installation of secondary grouting used fine stone concrete strength than equipment should be concrete foundation high level. When with no clear way installation equipment, the foreign design requirements, grouting material day compressive strength to achieve 30MPa, 28d compressive strength to 60MPa, or even higher (such as steel casting). In order to meet the design requirement, in raw materials for BT-6022 a lot of experimental research ratio, determination of the compressive strength, flexural strength of the range value table 6.表 6 BT-6022的抗壓抗折強度 MPaTable 6 BT-6022 compressive flexural strength MPa

抗壓強度			抗折強度
1d	3d	28d	1d	7d	28d
30～40	40～55	60～75	6～8	10～14	12～14

　　從表 6 數據可見，BT-6022的早期和后期抗壓強度都達到國內外設計要求，抗折強度與普通混凝土相比更有優越性。因此，可以在有早強、高強要求的國產和進口設備的二次灌漿工程中使用。　　From table 6 data shows, BT-6022 early and late compressive strength at home and abroad, the flexural strength design requirements compared with ordinary concrete more superior. Therefore, can early strength, high requirement of domestic and imported equipment of secondary grouting engineering in use. 四、其它性能指標Four, other performance index1 、鋼筋粘結強度1, steel bonding strength　　對圓鋼筋一天的粘結強度已超過 6.0MPa ，對螺紋鋼筋一天的粘結強度已超過 13.0MPa 。因此， BT-6022灌漿料可部分代替環氧樹脂作地腳螺栓的錨固材料。　　On circular reinforced day the bonding strength has been more than 6.0 MPa, screw steel day the bonding strength has exceeded 13.0 MPa. Therefore, BT-6022 grouting material will partly replaced epoxy resin as the anchor bolt anchor materials.2 、抗滲性2, penetration-proof quality　　BT-6022灌漿料的抗滲水性較一般防水混凝土能力好得多。機油滲透率、油滲深度、強度增長率等多項試驗表明，該材料浸油后強度不降低，耐油滲性能好。　　BT-6022 grouting material anti-permeability water is more general waterproof concrete ability is much better. Oil permeability, oil infiltration depth and strength growth etc. Several experiments show that this material leaching after oil strength not decrease, oil resistant permeability good performance.3 、低溫和凍融性能3, low and freeze-thaw performance　　BT-6022具有良好的低溫性能，在冰箱 -5℃ ，環境 -10℃ 的條件下使用時，其 7d 抗壓強度不低于 30MPa 。轉為標溫養護后，其抗壓強度立即上升，能滿足較低溫度下的工程設計和施工要求。低溫型的 BT-6022 在凍融后強度幾乎不損失。因此，可適用于在凍融環境中的設備安裝工程。　　BT-6022 good low-temperature performance, in the refrigerator -5℃, environment -10℃ conditions when using, its 7d compressive strength of not less than 30MPa. To standard temperature curing, after the compressive strength immediately rise, can satisfy the under low temperature of engineering design and construction requirements. Low temperature type BT - 6022 in freeze-thaw after almost no strength loss. Therefore, can be applied to the frost environment of equipment installation project.4 、不導致鋼筋銹蝕4, without causing corrosion of reinforcement　　BT-6022灌漿材料往往與鋼筋和鐵制設備基礎長期接觸。試驗表明其系列產品在自然電位處于鈍化狀態 (0～300mV) ；試塊劈開后，所埋的鋼筋無腐蝕。因此，可以說BT-6022灌漿料不會導致鋼筋銹蝕。　　BT-6022 grouting material often with steel and iron equipment foundation long-term contact. Experiments show that the series product in natural potential in passivation state (0～300mV); Test-components split after buried reinforced non-corrosive. Therefore, it can be said that BT-6022 grouting material will not cause the rebar corrosion. 五、結論Five, the conclusion1 、BT-6022灌漿料有很好的流動性，適用于設備的二次灌漿、地腳螺栓錨固和工程維修；1, BT-6022 grouting material has good liquidity, applicable to equipment of secondary grouting, anchoring bolt anchor and engineering maintenance;2 、BT-6022灌漿料的初凝時間、終凝時間和膨脹率均滿足工程設計和施工要求；2, BT-6022 grouting material of initial set time, final set time and inflation will meet the engineering design and construction requirements;3 、BT-6022灌漿料具有很高的抗壓強度，完全可滿足國產和進口設備對灌漿體強度的要求；3, BT-6022 grouting material has high compressive strength, can fully satisfy domestic and imported equipment for grouting body intensity requirements;4 、BT-6022灌漿料與鋼筋的粘結強度高，可替代環氧樹脂作為地腳螺栓的錨固材料，且在自然電位下對鋼筋無銹蝕作用。4, BT-6022 grouting materials and reinforced the bonding strength is high, can substitute the epoxy resin as the anchor bolt anchor materials, and in natural potential under no rust role of reinforced.5 、BT-6022 灌漿料的抗滲水性好，抗油滲和浸蝕能力強，低溫條件下強度較高，且抗凍融性較好。5, BT-6022 grouting material anti-permeability of oil and water resistance and good permeability and unpolluted ability, high strength, low temperature and freezing-thawing resisting better properties.　　BT-6022 灌漿料具有良好的耐疲勞性，在 200 萬次疲勞試驗后，靜壓強度仍很高，而同條件下普通同標號混凝土在 15 萬次時就已破壞。據國內外資料顯示，摻灌漿料的彈性模量都低于普通混凝土，這有益于減緩設備的振動荷載對基礎的沖擊壓力。在BT-6022灌漿料膨脹觀測過程中，灌漿料膨脹速率存在一定波動，經數次試驗分析，排除試驗誤差后的影響，可能是受水泥熟料中不同礦物水化的影響，這一機理尚待證實。總而言之， BT-6022 灌漿料工程性能佳，適用范圍廣，是一種很好灌漿材料。　　BT-6022 grouting material has good resistance to fatigue sex, in 200 million times fatigue test, static strength is still high, and under same conditions with label concrete in ordinary 150,000 times when they have been destroyed. According to the domestic and foreign material shows, mixing with grouting material of elastic modulus is below normal concrete, it is good for slow equipment vibration load on basis of shock pressure.Grouting materials on BT-6022 expansive observation process, grouting material expansion rate fluctuation, there exist certain by several test analysis, eliminate the influence of test error may be due to the cement clinker different mineral hydration, the influence of this mechanism is yet to be /confirm/ied. In short, BT-6022 grouting material engineering performance is good, application scope, is a kind of very good grouting material.
