From　review　of　the　background　of　concrete　construction　in　China,　technical　suggestions　are　given.　It　is　the　new　requirements　for　concrete　materials　and　technology　to　be　ecological　in　21st　century,　including　resource　saving　and　environment　friendly.　Utilization　of　substituting　fuel　and　lowered　firing　temperature　are　both　energy　saving　and　environment　friendly.　The　reliability　and　safety　of　concrete　materials　and　technology　is　closely　related　with　the　ecological　environment.　From　a　viewpoint　of　the　ecological　environment,　it　is　important　to　produce　concrete　on　an　approach　both　energy　saving　and　environment　friendly,　for　example　by　use　of　solid　wastes　and　waste　water.　It　is　also　imperative　to　design　strength　of　concrete　for　structures　with　both　enough　strength　and　strength　reserve,　to　provide　them　with　superior　resistance　to　environmental　degradation　factors.
