FDN naphthalene formaldehyde

FDN Naphthalene Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. FDN naphthalene formaldehyde also allows concrete to be produced with very low water/cement ratios at low or normal slumps. FDN Naphthalene Formaldehydeis ideal for use in prestress, precast, bridge deck or any other concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation FDN Naphthalene Formaldehyde can be added directly or added in after dissolved. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%.
