Abstract: ERANA, LEE ARIOS G., MARZO KURT KENNETH C., and ROSARDA, ROM MARIE A. Sawdust as Supplementary Aggregate to Concrete Hollow Blocks Research Study Science High School (General Science College of Education, Cavite State University, Indang Cavite May 2017. Adviser: Engr. Cesar Carriaga. I'he study entitled "Sawdust as Supplementary Aggregate to Concrete Hollow Blocks Production "was conducted from December 2016 to January 2016 at Alulod, Indang, Cavite to produce concrete hollow blocks with sawdust and lahar materials as supplementary aggregate. Specifically it aimed to: a) determine the compressive strength and density of concrete hollow blocks with different amount of sawdust, b) determine the amount of sawdust as aggregate that produce good quality hollow blocks in terms of compressive strength and density; and c) determine the cost of production of the produced concrete hollow blocks with different amount of sawdust as an acyoregate. The study had five treatments with three replications each. The five treatments used were as follow: To. Commercialized Concrete Hoiiow Blocks (CHB); T l. Cement 50%, Lahar — Sawdust 5 % . T2 Cenlent 5004 Lahar — 40%, Sawdust - 10%; Cement 50 0/0, Lahar— 35%, Sawdust — 15%; T4. Cement — 50 %, Lahar— 30%, Sawdust. The materials used such as cement, lahar, and sawdust ware collected and proportioned per treatment. Sawdust was dried and lahar was screened to get its finest pieces. When the mixing is done, the mortar was poured in the ground and the proportioned saw dust was applied. The mortar and saw dust were mixed thoroughly using shovel and cement were mixed thoroughly with water using electric mixer. After 28 days, the produced hollow blocks were transported to Associated Services and Testing Center (AS TEC) in Pala Pala, Dasmarinas, Cavite to determine its compressive strength, It was also transported, measured and weighed in one of the researcher's residence in Alulod, Indang, Cavite to determine its density. The best treatment is Treatment I with 5% amount of sawdust replacement of lahar. Based on the results of the study, Treatment I had the highest compressive strength of 393.3 psi and also had the highest density of 1.607 g/cm3
