Abstract

Concrete Paving Block (CPB) is a building material composition made from a mixture of portland cement, sand / aggregate and water and with or without other additives. As a choice of road construction, other than asphalt road and concrete. Paving is rich in colors and patterns for its applications. CPB deliberately designed with an attractive style to suit the tastes of the market and designed with the power that suits the needs. CPB compaction technology has been done in the community according to its funding capability. The simplest compacting technology to the most modern and expensive is manual compaction technology, vibration blocking technology, hydraulic pressure compaction technology and the most modern technology is vibropressing. The most modern technology certainly produces the best pressure quality. Two manual compaction technologies and vibrating blocks are very difficult to produce high quality while the compacting technology with hydraulic pressing is most likely to reach a quality close to modern technology. Therefore, in the following research is how to get the best CPB quality by using hydraulic pressing compaction technology using some methods. Stabilization of pressing technology on making concrete paving block used is mix design with variation of FAS, mix design with variation of fly ash and mix design with variation of ash content. from testing it was found that FAS above 0.5 has a compressive strength tends to decrease from all test behavior. Medium controlled Fas both fly ash and rock ash content, will tend to have a compressive strength that increases to levels of 20% of cement content. But the pressing technology on CPB making is still difficult to penetrate the strength figure of 300 kg / cm2
