Abstract: According to examples, a method may include pouring a fluid ultra-high performance concrete (UHPC) mixture into a cavity, thereby providing a UHPC having at least one exposed surface. The method may include applying a liquid polymer onto the exposed surface of the UHPC, thereby providing a layer of liquid polymer onto the at least one exposed surface. According to examples, the method may include rolling the layer of the liquid polymer layer on the at least one exposed surface of the UHPC with a spike roller having a plurality of extended spikes. In some examples, the rolling may be applied with a predefined amount of pressure to cause the extended spikes to pierce the exposed surface of the UHPC, to incorporate the liquid polymer into the UHPC.
