<p>AN ADDITIVE FOR DRAINAGE MIXES COMPRISES HYDRATED LIME. IN ONE SPECIFIC EMBODIMENT, THE ADDITIVE IS HYDRATED LIME OF 80-100a(OH)2 AND HAS PARTICLE SIZE DISTRIBUTION OF 0.05-300µm. IN ONE PREFERRED EMBODIMENT, THE HYDRATED LIME HAS A PURITY OF AROUND 80-100a(OH)2, AND A PARTICLE SIZE DISTRIBUTION OF AROUND 8-12IN THE RANGE OF 0.05-0.5µm, 73-90IN THE RANGE OF 0.5-75µm AND 0.5-7IN THE RANGE OF 76-300µm.
