摘要: An agent and method for modifying a surface layer of hardened cement structures or substrates with use of the agent which comprises in a specified ratio of an alkali silicate solution and a sodium naphthalenesulfonate-formaldehyde condensate. Said agent has an excellent stability and a remarkable permeability into the cement structure to form a deeper strengthened surface layer thereon.
