剪切型钢纤维在使用外加剂时注意事项
1） 根据使用目的，选择品种，并根据技术经济进行比较确定。
1) Select varieties according to the purpose of use, and compare them according to technology and economy.
2） 所加掺量应按所用品种，并根据使用要求，施工条件，拌合的原材料等因素经试验确定。掺量以水泥重量的百分率表示。
2) The dosage should be determined according to the variety used, and according to the use requirements, construction conditions, raw materials and other factors. The amount of admixture is expressed as the percentage of cement weight.
3） 掺量为1％以下的外加剂（如高效减水剂）应以水溶液掺入为宜。
3) Admixture with less than 1% content (such as superplasticizer) should be mixed with water solution.
4）注意外加剂与水泥的适应性。
4) Attention should be paid to the adaptability of admixtures to cement.
5）外加剂的性能应符合现行标准《混凝土外加剂 应用规程》的规定。
5) The performance of admixtures should conform to the current standard "Specification for the Application of Concrete Admixture".
另外，根据需要和可能，在钢纤维混凝土中还可掺入一定量的粉煤灰或硅粉等混合材料，以改善拌合料的和易性，节约水泥用量以及提高强度。其拌合材料性能应符合现行标准《用于水泥和混凝土中的粉煤灰》和《用于水泥中的火山灰质混合材料》的规定，其掺量可通过试验确定。
In addition, according to the needs and possibilities, a certain amount of fly ash or silica fume can be fangdaomen.89ix.comdiankonggui.89ix.com tiepuyi.89ix.comtanceqi.07858.net bianyaqiyj.37ix.com.cngangguanh.37ix.com.cnadded into the steel fiber reinforced concrete to improve the workability of the mixture, save the amount of cement and improve the strength. The performance of the mixing material should conform to the current standard "Fly Ash for Cement and Concrete" and "Volcanic Ash Mixture for Cement", and its content can be determined by test.
