| 5. | ( 2 ) according to national building mortar design regulations ( nbmdr ) , and applying to scientific avenue of orthogonal design experiment , performance and impact factors of dry - mortar produced by localizable phosphor slag , flying - ash , ordinary silicate cement , and yellow sand ( 2 )根据国家建筑砂浆设计规程,应用正交试验分析等科学方法,试验研究了用本地磷渣、粉煤灰、普通硅酸盐水泥、黄砂等原料配制的干拌砂浆性能及其影响因素。 |
| 6. | The one of most important factor of affecting durabilities in construction concrete is chloride deterioration . the chloride penetration current exceeds 2 , 000 coulomb in the no mineral admixtures silicate cement , using 30 % ~ 40 % fly ash it falls to 800 coulomb and the 60 % micro - slag falls to 500 coulomb ; though silica fume reduces penetration current , it deteriorates the workability of concrete 氯离子侵蚀是影响混凝土结构安全性最重要因素之一,不掺加任何矿物掺合料,氯离子渗透电量一般大于2000库仑;粉煤灰掺量在30 40 ,渗透电量达到800库仑;矿粉掺量在60左右,渗透电量达到500库仑,并具有较高的综合性能;硅灰可以改善混凝土氯离子渗透能力,但恶化了混凝土工作性。 |

( 4 ) the feasibility of producing dry - mortar is analyzed , replacing sulphur aluminate low alkalinity cement by silicate cement . ( 5 ) study impact of the water quantity of sand on the strength of dry - mortar , and it is concluded that water quantity of sand can influence strength effectively and must be controlled seriously in production ( 3 )试验研究了用磷渣替代黄砂配制干拌砂浆的可行性; ( 4 )试验研究了用硫铝酸盐低碱水泥替代硅酸盐水泥配制干拌砂浆的可行性; ( 5 )试验研究了砂含水量对干拌砂浆影响,发现砂的含水量对干拌砂浆的强度影响较大,在生产中必须严格控制砂的含水量。 |
