UPDATE 1-Holcim in C$630-mln bid for St.Lawrence Cement

ZURICH, May 14 (Reuters) - Swiss-based cement group Holcim (HOLN.VX) said on Monday St. Lawrence Cement group STa.TO had recommended an improved C$40.25 per share cash offer for the Canadian company worth a total of 630 million Canadian dollars (US$567 million).

Holcim, the world's second-largest cement maker which is in the middle of an acquisition campaign, said in February it would launch a buyout bid for the remaining shares in St. Lawrence Cement it did not own, saying at the time it would pay C$36.50 per share in cash.

The move comes as the industry consolidates with recent takeovers by Holcim in India and bigger rival Lafarge's (LAFP.PA) full acquisition of its North American subsidiary.

Holcim said its revised offer represents a 33 percent premium over a weighted average trading price.

Holcim already owns 44 percent of class A subordinate voting shares and 100 percent of class B multiple voting shares, representing approximately 79 percent of the company's total votes.
